love all the buttons, very precise mouse!

programmable buttons are great and dsi speed has more than enough settings

The mouse has a very loud squeak when clicking the left mouse button, very annoying and does not always accept the click.

Its smooth and has a nice click when pressing the top two mouse buttons

cheap plastic, cheap buttons, it got returned

Have kinda a big hand so the buttons are perfect in my opinion

That big red button on the left side of the mouse is very awkward to use

I love the programmable buttons

The main problem I have with the mouse is the left/right buttons have different button pressures to actuate a click.

The buttons have already broken.

you also get the rgb lighting to match your set up and can easily see all the number buttons and the rest of the mouse with the scroll wheel light

The buttons don't hold up too well though

Great replacement for my Razer Naga, while I was on a smaller budget, same buttons on the side... loved that I could change my cursor speed from my mouse

The buttons on the side are all easy to press the few in the back are a little hard to reach but over all nice

I plug it in and check all the buttons to see if they work, clicked the 6 button 2 times and it broke

kinda not... somewhere in between mechanical and not... the little red button is not a rapid fire mod button nor is it actually a programmable button... mouse is extremely comfortable for someone with big hands...

Using the disk to setup the program on your computer was an absolute breeze, and customizing the buttons wasn't too difficult either (if you've used a gaming mouse/controller before, you probably will have an easy time with that, too)

Im a large guy, and my hands are pretty strong and after two years, I snapped off the left click button, but I am honestly impressed it lasted me as long as it did to break it

The Perdition has rows of 3 buttons in a zig-zag valley form so you will not mistake the first 3 buttons for the next 3 and so on

Further, the software supports five different profiles, so you can load five different sets of shortcuts for each of the 15 extra buttons on the mouse (you could actually change the function of the left and right click buttons and the wheel if you wanted to, too)

The right and left mouse buttons are far more sensitive than a regular mouse, but are incredibly easy to get used to

The buttons all work, nothing sticks, nothing fades

The buttons are all accessible and have a nice feeling.

All the buttons work correctly and the program that you use to program the buttons is very intuitive and easy to use

Other than that, it feels great in the hand, buttons aren't super loud, easy to click, and easy to find.

Also the lighting on the mouse is very nice, and the button at the top left is nice, but not as nice as the 2 buttons below the scroll wheel (used normaly to change DPI, I remapped to Alt+Tab and Alt+Esc)

- The side buttons (the number buttons) are not the best, but that is standard for these type of mouse's.

The weight is nice, (and adjustable,) the color and brightness settings are very cool, the buttons are easy to configure and use, and it feels fantastic in my hand

The buttons are easy to learn how to use.

what probably killed my left button, haha

The extra buttons are a GODSEND

Sometimes the buttons on the side can come very mushy and soft

People who have started that the 10-12 buttons are awkward to press probably haven't used other gaming mice of this variant

Works well, buttons on side can be pushed on accident because there is no good place to grab the mouse other than the buttons.

Responsive buttons and the on the fly DPI switch is really nice

You won't be able to use their software or get to program the keys on Mac, still the buttons work 1-9

Responsive to movement, all the buttons were easy to use, and it was easy to setup with their software

I love how it lights up and you can change its colors, the side buttons work no problem and its easy to change the buttons as well, and the added weights inside the mouse are awesome as well.

Love that you can change the little weights inside and the buttons are super responsive and it's been working well for the mmos I play, especially Elder Scrolls Online!

This one is half the prize, great dpi control, and the shape is great for smashing many buttons at once.

The number 2 button does not work unless pressed so hard

For the first day or two I had to kind of check to make sure I was clicking the right button out of the 12 there are, but after a couple of days I knew exactly which button I was pressing all the time

The buttons themselves are relatively easy to push, but not so easy that you will press them when you don't mean to

Compared to the Naga, I think its buttons are far easier to get to

Bought this mouse as a replacement to my old Naga that had a blown out right mouse button

It feels solid and all the buttons feel sturdy.

Left button quit working on one of my main mouse's

The one slight complaint he had was that going from a no-macro mouse to this one, the buttons depress pretty easily, so it takes a bit of getting used to in order not to accidentally push the ones nearest to the thumb when lifting the mouse.

It's got a great texture to it and the buttons are easily accessible.

I attend an engineering school and have to work with Solidworks frequently and it saves so much time having all my buttons hot keyed on my mouse, don't really have to use my other hand at all anymore

buttons are a bit stiff but you cannot beat this price

PROS:-Nice texture, almost like a very fine grit sandpaper-VERY custimizable (light color/brightness, dpi, weight)-Lighting is tasteful and not overdone (back-lit logo and thumb buttons as well as a color coordinated scroll wheel indicating dpi profile)-Triple-click button-Braided chordCONS:-Oils can be difficult to clean due to texture, but routine cleaning helps limit this-Somewhat loud click, but generally not noticeableOverall, this is an awesome mouse at an affordable price

I love the mouse, its fantastic for gaming, and i use it in smite all the time, you can macro every button which is super good, the only problem i have is my left clicker broke yesterday, and it says it has a 2 year protection plan, yet amazon wont let me send it in, not sure if this is the place to ask how i do a return, but some help would be super apreciated since i love using this thing.

The Middle buttons 2, 5, 8, 11 are sometimes difficult to press during more intense game moments such as PVP combat, but the mouse performs better than my expectations overall.

In my opinion the mouse is better than the Razor counterpart as far as features (though the buttons on the Razor Naga are easier to use in the beginning).

The additional programmable buttons on the side have really made gaming easier for me

Of course you have to consider the LEDs as well, I absolutely love the deep red logo and buttons

Dedicated fire button says FPS, but 12 "programmable" keys on the side says MMO or something on the same style of world of warcraft

is trash because of how hard the buttons are to click the I release that wasn’t the problem it was how I used the mouse with the wrong

Right trigger button is stuck, and doesn't click half the time

Best 8+ button mouse I've seen yet (16 or so here)

Even Corsair struggles with software, their mice are great but the drivers are trash.- Good button placement and ergonomic design.

The buttons are decent

The buttons are easy to hit and easily accessible.

The buttons on the side and DPI adjustment buttons are fantastic and have a great tactile feel

I also love the programmable buttons!

12 buttons on the side 9 buttons are reachable comfortably (last 3 takes moving the hand down the mouse to use them, though)

Pros- Cheap, feels good, 12 buttons, high max dpi, amazing color range of the buttons, simple minimalist

Pros- Cheap, feels good, 12 buttons, high max dpi, amazing color range of the buttons, simple minimalist

The buttons aren't hard to press but they do take some pressure, so I haven't noticed any misclicks

Can set up to 5 different button profiles (configurations) customize the weight and all the buttons are easily accessible

While the number pad was easy to pick up, pressing the buttons themselves was a hassle and requires a bit of extra force than I expected

Did not specify compatible operating system (windows 7-10) buttons felt a bit stiff, but over all a great mouse.

so I am sure that I press the correct button

Love the mouse, great usability and the buttons are very good.

Other than that, it feels great in the hand, buttons aren't super loud, easy to click, and easy to find.

, I like the size and texture and the angled side buttons, I find them much easier to use by touch

No issues as of yet and love the quick fire button for lots of shooters or even for World of Warcraft

The weight is good, the buttons are responsive, and it is a nice sized mouse

Mouse feels great and love all the buttons, pretty much the reason I purchased it

It feels slightly awkward using the buttons on top of mouse besides left and right clicks

The 12 buttons work just like a numpad, allowing for a lot of keybindings.

not exactly ideal button placing due to the tilt of side buttons, and I find the red button in the corner of the left click practically useless as it only acts as a lett clicker also

The mouse feels perfect in my hand, and is comfortable to use!All buttons are easy to press, aside from the number buttons on the side, would have given 5 star rating, but I sometimes find that I need to press a little harder to press the buttons on the side

the 7th and 10th button on the side are a little awkward to reach, but it's perfect otherwise

The buttons all feel sturdy have give a satisfying, but quiet click when you tap them

Pros:-looks cool-custom dpi-nice texture-braided cord-gold plated end-customizable color-12 side buttonsCon:-Left click gets softer and softer the more you use it-Left click is only fixable by pulling the left plastic tab up to reset the switch-Laser is trash on it (extremely finiky with the surface u use)-12 side buttons are extremely soft and you cant tell if they are fully depressed and if they are registered.-Side buttons aren't laid out well-Side buttons don't work all the time-Mouse lag (like the old 2011/2012 Nagas)DONT WASTE YOUR

Windows supports up to 5 buttons on a mouse.

The back buttons are a little awkward, but this mouse works great.

I find myself ALWAYS accidentally hitting the right mouse button (the buttons are extremely sensitive).

Love the buttons on the side.

The side 12 buttons are incredibly useful

The buttons on the side feel nice and the lighting is good but the software is a little craptastic.

Good thing the expensive G700 is also wireless (wish the Perdition was).On the white mouse the right click button occasionally would catch on my finger resting on the right side of the mouse and pop "loose" from the mouse; luckily it didn't break off the 3 times I had to press it back in

I left the room for about a minute and when I came back my squirrel monkey had BROKEN the left click button completely off (just ripped right through the plastic)

Now the right click button barely works

The dpi will change on its own, either that or the button is so sensitive that anything presses it

This mouse came more decked out than I'd thought originally, it's perfect for my mmo's with the 12 side buttons, and perfect for shooters with the dpi adjusters and rapid click button alongside the left clicker

One problem though with my mouse is that the number 8 side button does not work on my mouse which is not to bad as 11 buttons are already enough and I tend not to use the back 6 buttons that often.

Left number buttons are easier to differentiate because of their different angles whereas in Razor they feel same

You can set this thing to stupid speeds and the quick buttons in the

The side buttons are comfortable and I don't find myself ever hitting the wrong button

I would rather lose the left most top button and move the numbers further forward and either spaced further apart or bigger.

Not a single button of the 12 gives a satisfying feel really

I would rather lose the left most top button and move the numbers further forward and either spaced further apart or bigger.

So i start to mash them harder to see if it was just a stiff button...nothing.

The buttons underneath the wheel cannot be programmed with WOW or the top left red button

The buttons on the side are awkward, but I guess it's nice to have them should I need to hunt and

The two central buttons below the mouse button are not realistic for me to use in combat but outside of

When we got it in, the #5 button was difficult to push and would hardly register anything, but the company was quick to offer a redund/replacement and offered great customer service the entire time we corresponded.

I dont know if its just my mouse because I don't see other people having this problem but its there.2) Side buttons - After coming from back to back naga's the side 1-12 buttons are extremely crisp and give you great feedback on when they are pressed

The buttons and laser are very responsive

I started to love the buttons

The buttons all work as advertised and it gives you many more map-able keys than your standard mouse, but don't expect this to last you very long before it breaks

The buttons are responsive, easy to press, and the slight angles of the buttons makes finding the correct button easier

The back buttons are a little awkward, but this mouse works great.

I loved the programmable buttons on the side.

button on bottom of mouse is great, highest setting requires very little movement

The buttons are easy to program in whatever game your are playing.

After a few months of using this in Fortnite, CS:GO and other games, I can confidentially say this is a fantastic mouse, button for everything

not exactly ideal button placing due to the tilt of side buttons, and I find the red button in the corner of the left click practically useless as it only acts as a lett clicker also

It'd be that the number buttons could use a lil more definition as its kind of hard to tell them apart without looking.

The only fault I can find with the mouse are the button above the scroll wheel which i use for forward and back while browsing, the back button is just a bit too far up for comfort, but perhaps the feeling will fade over time as I get used to the mouse

Plus the customized binding allows you to disable button so you don't have to use all 12 if you don't want to

the buttons on the new M901-1 were much harder to press and didn't have a crisp feel when the switches activated

The buttons are a little strange and kind of hard to press at first, but only because I was so used to the Naga buttons being smaller

Apparently, the top left and right click buttons on the black one are more flush with the housing and there is zero chance of this happening with it

Angled side-buttons and the lightly textured center (5/8) buttons are perfect.

The buttons on the side aren't nearly as useful as I'd imagined, however, and they mostly go unused.

: I wish the Rapid Fire button was just the Forward and Back buttons like the original Razer Naga

They are angled so at each other so you can really tell what you are hitting to help avoid accidental presses and improve accuracy/speed of the right button.

My favorite is the two buttons below the click wheel

Mouse works great and I needed it as a replacement, but the buttons, especially on the side, are too stiff and have hurt my fingers from the pressure

The red button near the index finger that is supposed to be a quickfire button did not work in csgo however i suspect that the game has something

the number "6" button is permanently pressed

Never thought I would say this, but there is such a thing as a button being too sensitive

The DPI button's are nice and out of the way, in a concave like wall around

Mine lasted about a year before the 9 button stopped working

What I would change is that I personally would like the programmable number buttons on the side to be shifted slightly forward (like 1/4-1/2 of a centimeter) because in pvp the back 3 side programmable buttons (10,11,12) can be somewhat difficult to press quickly

The buttons are wonderful

The buttons themselves feel nice and are easy to find

The mouse feels good in my hand, is the right size, and the buttons are easy to program with the software

It took a while to get used to the size and the convenient side buttons, which you can program, but after a few days with it I find it hard to imagine going back to a normal mouse.

I hate the tilt buttons on so many mice nowadays that makes pressing middle click alone more difficult than it should be

The left click button seems too easy to press, and has very little travel distance

good programmable gaming mouse.took a bit to figure out how to make a mouse click delayed macro where the mouse held a key down for a time to charge up a weapon on a game and then release it.side buttons are a bit on the small side but workable (i have large hands lol )over all feel of the mouse is comfortable

As it was a great mouse until the button became faulty, I'm willing to give this mouse another try

It's made out of a nice smooth plastic which feels lovely against my hand, the scroll wheel turns very smoothly as well, and the middle buttons are much easier to press than the Naga's, due to their bigger size

The buttons on the Perdition are a rounded-corner matte plastic vs. the squared smooth plastic buttons on the Razer Naga 2014

You probably won't need the 16,400 dpi, but the complete customization options of the top buttons, side buttons, dpi, and colors is something that everyone can use

All buttons work and feel great still!

Such an upgrade from my previous mouse(redragon nemanelion), having the 12 macro buttons on the size is absolutely amazing

I liked the design of the mouse and all the buttons so well that I bought another recently

The buttons on the side especially 1, get jammed and cause my computer screen to freeze and stutter even though I'm not pressing on it

The two top dpi adjustment buttons should be raised higher instead of being essentially flush with the top of the mouse.

Affordable, Stylish, Many many user programmable buttons, Weighted

Each button is programmable as well, although I haven't programmed any yet

Note that when you get the mouse the buttons may be a bit difficult to press, but with some decent amount of usage the buttons will get much easier and function better.

The mouse is well designed and fits nice in my hand, but the 12 buttons on the side are kinda awkward to press

(I have experienced when clicking the left mouse button and then attempting to click the right button it mostly will not activate and have to press twice which in gaming is a solid NEGATIVE).I bought the white one, is the black one any different or better

I did some research and discovered that many other people were having this same issue; however, I really loved the programmable buttons on the side.

My one complaint is the single red button doesn't seem to work for me

This is the cheapest 12 button mmo mouse on Amazon, and it is solid and durable (surprise)

I really love the extra programmable buttons; they increase usability tenfold

After two years the main button fell off and had to buy a new one.

The top buttons were fine.

The way it is set up it is easy to feel the correct button (for firing grenades, or switching between weapons) .

- The side buttons (the number buttons) are not the best, but that is standard for these type of mouse's.

so I use the number buttons to type things like phone numbers and birthdays without leaving the mouse

Right mouse button would not work when just plugged in

The mouse is nice and conforming to my hand and the buttons are easy to reach took about an hour to get my thumb adjusted to using it vs the Naga epic!

Very good design, all the buttons in the right places

The only con is that the buttons on the side may become a little awkward to hit and it may be difficult to differentiate which button is which

It doesn't feel right unless it's over the right button

I love the trigger button

The buttons are nice and work well

The buttons on the side are awesome and the software is helpful you can have different modes of the mouse

The buttons are nice and work well

I love the 12 programmable buttons on the side which I have mapped for things such as webpage forward and backward, volume up and down, and the Esc key

I have owned a Razer Naga and Naga epic both had dead buttons within 6 months

so you dont miss press the wrong button

I have only had the mouse less than three months, of minimal use, and the 7 button on the side of the mouse acts like it's the 8 button when pressed

That button makes the M901 a stellar partner for my laptop, since the portable machine lacks all the extra thumb-activated modifier keys that my main PC nerd-gamer keyboard has; I bind the button to ctrl and instantly have 12 mouse-hand modified buttons

I love the look and feel of the mouse, the buttons are all very good quality, I find that it is a little on the light side even with all of the weights in it, but that's not a problem

The first 6 buttons are easy to reach, not so much on the last 6

But sometimes I still end up clicking accidentally on the left or right buttons and it messes me up.2.

Next, the buttons are harder to press compared to the Razer Naga

The Naga does have slightly more comfortable ergonomics and easier buttons, but trust me: the difference is not worth an additional $30, or even $10

buttons are great on the flyDurableAdjustable weightEasy/instant installCons - The only negative I have that keeps this from being a 5-star is I noticed another customer mentioned a grinding section on the mouse wheel

After light usage and a little over a year, buttons 1 and 8 have stopped working

Bad:It is hamstrung by lack of software support for these amazing buttons

It does not support button 4 or button 5 click that are recognized by the windows OS.

The buttons on the side are very convenient, at first they are hard to distinguish apart, it would help if some of them had dots for

Fits my hand perfectly, the buttons are easy enough to get use to and the mouse movement speed was a little

It should also be noted that the little red button to the left of the scroll wheel is too impractical to be used with frequency, and the scroll wheel does *not* move to the left and right

This is a pretty amazing mouse, definitely worth the money if you play with your entire palmPROS-All the buttons feel very nice to press and are easy to reach (although sometimes it's hard to reach the numbers 7,8, and 9 on the side) except some which I'll talk about later-The buttons on the side aren't a distraction, even if you play an fps like me.

All the buttons work as if I opened it yesterday

Some Pros:- extra button next to the left click seems useful- weights are a nice touch, but not one I will ever care to use- on the fly profile and DPI switching built in is very

If you play any computer game you are going to love the 12 buttons where your thumb is

The macro button on the side are easy to setup and work great with Final Fantasy XIV ARR and Heavensward.

The buttons on the side are easy to press, but buttons 7-12 might require some awkward thumb bending

The buttons feel good and the mouse doesn't feel cheap

I would rather have the two buttons near the left click on the Naga as opposed to the one near left click and two under mouse wheel on the perdition

Pros:- Best button setup in my opinion.

Save your money buy a good mouse side buttons are so hard to push compared to a decent mouse don’t rush buy a good mouse.

They should have a nice crisp press to them, so don't accept one that has weak mushy buttons, return it for a good one

The software for remapping the buttons is really easy to use

In other words I cannot feel the buttons well enough to use more than maybe 6-8 of the side buttons due to placement

only problems are the 12 buttons are a little hard to hit accretly

i am able to find that sweet spot.the main button, left mouse button, can feel a bit stiff and squeeky at times

I bought this for my son and the first one I had to send back because the left main button refused to work

I love the quick buttons on the side

The buttons on the side are soft and close together, easy to find/identify with out looking.

Since the side buttons are all curved to assist you in finding the right button it was difficult for me to transition from my Razer with an even flat edge of buttons, but the more I get attuned to it the more Im believing the curve assists in finding the correct key Im looking for

I like the programmable fire button on the left side of the top of the mouse

not supported on linux, as far as I can tell) included, allows for different dpi's across BOTH X and Y axes and different color schemes via LED, well placed buttons on side, a high maximum dpi, and a good feel in the hand

Lots of great buttons for gaming.

I have a friend who has a razor that he bought about 6 months before I got this mouse, and his razor's buttons are going bad, this inexpensive treasure is still doing great though!

It's really comfortable and the additional button on the left for my index finger is invaluable.

the button closest to the mouse wheel is relatively easy to press without changing to a claw grip.

I've had far worse luck from logitech who charges much more usually for it's gimmicky mouse wizardry which also suffer a mysterious malady of no software support for their fancy meta buttons.

I love having the buttons on the

12 buttons on the left side (by default, it behaves like a numpad with buttons 1-9 being exactly what you'd expect, 10 is mapped to 0, and 11 and 12 go to + and - respectively), plus a secondary fire to the left of your left-click which behaves like a rapid-fire by default (not terribly useful, but it's good for quickly highlighting text)

Instead, it requires you to repress the button several times to get it to finally fire

specially at PvP, u cast your skills better than others = win!
