Sensor is terrible, missing buttons

Works great but the buttons are a little too easy to push.

The buttons work OK, but the cursor randomly "freeze"

But for those of us that game or are otherwise computer "Power users", the fact is the button on the wheel is nearly unusable

I like the back and forward buttons and the mouse seems like it would be reliable for several years

I tried to open it up, the button became more loose and noisy

Middle button broken after TWO days of use.

I just received this item and there is no button on the thumb rest and no screen printing on the top button

Also two side buttons a scroll wheel and a top button.

Specifically, the click button (usually the left one) will prematurely fail and render the mouse difficult to use.

Programmable buttons are very helpful.

The fast scroll button is pretty cool

I love the back button and the scroll button has the option to have an infinity scroll or a slow roll

Best mobile mouse around, a bit heavy and center wheel button a little hard to push.

Broken, damaged button

Amazingly smooth mouse, the scroll wheel is amazing, it's the perfect size and weight, perfect number of buttons, the buttons feel great

The right button was starting to flake out, so I opened it up and "repaired" it, but after three months the left button was starting to go too

Wonderful mouse, very comfortable, though I disabled the "Application Switcher" button which I kept pressing by accident.

So, you are missing an important extra button

The left and right buttons tend to lose their function after a few years simply due to constant use.

So, the buttons and everything work great

I love the endless scroll and the back buttons

The customizable buttons make my job much easier

I love the form of this mouse, the side buttons I am so used to

The left and right click buttons rub together to where you cant click the left button without the right button going down as well

This last time, I'm a little disappointed as I finally needed it and opened it up and the right button when clicking squeaks.

Compact, fits in the hand well, and not so many buttons that you have to spend a bazillion years figuring out how to program them

, the middle button click its not perfect but good enough

The cheap plastic and bad design lets the left button and right button hits each other after using it for only three months

only forward / backward button.

The extra buttons are nice for working on spreadsheets

I love the thumb button.

The back/forward buttons on the side aren't contoured like the M510, and I loved that feature on the

It fits my hand much better, the side buttons work fine as forward and back buttons, and it perfectly fits in my bag

Great mouse, very comfortable, love the smooth scrolling and side buttons for back page/forward page.

The button doesn't work well and DPI control button doesn't seemed to work.

These mice are responsive and the back/forward buttons make navigating web pages easier

I was playing Resident Evil Revelations with this mouse and that game requires you to hold down the right click button to switch to aiming mode and press the left click button to fire

The button doesn't work well and DPI control button doesn't seemed to work.

Try reversing your left and right click buttons if you're not sure if it's a software issue

The buttons produce a satisfying click when used, and it tracks well, though I am using a cloth-covered neoprene rubber mousepad,

I like the programmable buttons

My magical application button, which I fell in love with, is no longer on the new mouse

The double-click of the left/right button starts, and its time to replace the mouse.

The customizable buttons are extremely beneficial, including the thumb button that you might not know was there just by glancing at the product details.

the scrolling is fast and I can even stop it with the middle button great product

, the middle button click its not perfect but good enough

This last time, I'm a little disappointed as I finally needed it and opened it up and the right button when clicking squeaks.

Squeeks when left or right buttons are used

So, you are missing an important extra button

If you don't like the forward and back buttons (I don't, I never use them on purpose and click them on accident a lot), then you can download software and set it to ignore those mouse inputs completely

The only gripe I have is that the back mouse button doesn't work on Macs, but I think this problem actually Macs in general not supporting the back button

The button is perhaps too sensitive for my tastes and is easily bumped/switched.

The button on the top allows to lock fast/slow scroll and the scroll buttons also works as middle button

the side-scrolling markings, free-scrolling wheel button markings and logo will rub off, from palm perspiration and friction, I imagine

Great product, very durable, long battery life, smooth function, useful back/forward buttons near thumb

The buttons work fine, but a mouse that doesn't move the pointer isn't very useful

I own 3 other M705 before this one, I use my computer for work a lot and all those 3 buttons got destroyed over years or usage

Love the scroll wheel and the side buttons

, if you would like a thumb button, you'll now have to order a M720 Triathalon mouse.

The button to change from smooth scroll to clicks is a cheap big button where the app-switcher button used to be.

The wheel has nice smooth scrolling OR clicky scrolling depending on position of the top button.

It's got just enough buttons for the functionality I want without being overly complicated

Cons:- Virtually no "middle button", very hard to press

right and left mouse, plus two thumb buttons along the side that are user configurable.

I love the extra hidden button that opens up every active window like Macs do

You can expect a 1-2 year life span of this mouse, depending how heavily you use it, before the left/right click buttons start to get faulty.

It's very plasticky and light, even with the batteries in; the buttons feel terrible

In contrast, similarly-priced mice I've had before this one would chew through batteries, fall apart over time (scoll wheels, buttons not working) and not work as well as the M705 on varied surfaces

Even when brand new, holding down the right button first, about a 1 in 10 times the left button gets jammed somehow making it impossible to use meaning that I have to release both keys and try again to get it to work

The buttons have a good feel and I like the rubbery texture on the thumb rest.

The left click button squeaks like crazy now and is almost unusable to left click stuff

Never-ending battery life, ergonomic, responsive, and just enough extra functions/buttons for business or casual computing

I'm a gamer and I love the side buttons and the smoothness of the mouse.

I like the different buttons. and that the scroll wheel can also do horizontal, and the scroll button can easily be changed to scroll quickly or precise.

once i figured out how to disable the lower thumb button, it was perfect.

I came back to this same mouse because the click is fairly 'soft' - in other words it's easy to press down the left and right buttons so it doesn't irritate my wrist as some other models do

This could have been the perfect business mouse except for one FATAL flaw: the right button is so sensitive that I click it accidentally several times a minute, which totally blows my concentration

Not among the best click-feeling buttons, but really comfortable.

Good tracking, nice button placement, easy to use

The buttons on the mouse are incredibly handy.

This mouse is nearly identical, but again that missing button is really frustrating because I used it all the time and because, according to the Logitech website and according to the Amazon product page for the mouse, that button should have been on the mouse amazon shipped

The right button menu optins just doesn't appear

great item, love the side button for back moves

Its been two months and the Left click button stopped working

I like the multiple buttons that are easily programmable

Different weight, different laser, missing the hidden button.

Stiff buttons and cheap cords

Great size, buttons on the side are in perfect location and just plain easy to maneuver.

The top buttons are a little flimsy, but otherwise work perfectly fine.

Wheel is nice and smooth (fast scrolling) and buttons to me are easier to press than the mx mouse

Just make sure you click on the top button so that the wheel doesn't spin so freely.

it left/right as well), and it's missing the thumb button

It works on almost every surface and has enough buttons to be useful

Having only ever used ordinary 2-button + wheel mice, the only issues I had were with the free-moving scroll wheel (which was solved by figuring out what the top button did) and the fact that the laser is on the left side underneath instead of the center (which just took a little getting used to)

The multiple programmable buttons are great

because I became reckless using it (pushing buttons ever harder) and mishandling it while putting it and taking it out of my backpack, I had to press the left mouse button quite hard to get it to work, eventually trying to fix it myself, breaking it and then regretting my negligence

Love the infinite scroll function and forward/backward side button for web browsing

Satisfying click buttons and scroll wheel

Also love the page forward & back buttons.

The button stop makin noise (still loose though) but stopped clicking and working

I love that button and use it all the time

but there is another button in the thumb gripaccurate and responsive wheel with unlock so you can free spin it or have it notched (helps to get to the end of long documents with one flick)CONS

The noise is really loud when you click both left and right button

while doing so a scroll wheel usually moves resulting clicking outside the link.- Button to "unlock" the wheel feels like an industrial one to turn on a heavy machinery, very hard to press and feels it jams on

Does not track well on all surfaces, buttons feel cheap to click

After 9 months of continuous, daily use, the free-scrolling wheel button marking is already beginning to fade into oblivion

When working in Word or composing an email in Outlook, using the right mouse button should bring up suggestions on a mispelled word

Like when I have filled out a contact form and about to submit it, the Boom, my thumb hits the back or forward button

That back button is just too convenient and drag and drop is very easy

Work very well, especially the programmable buttons.

Who can mess up the main mouse buttons

The extra buttons are also useful in many different programs

The buttons and roller work well

Love the infinite scroll function and forward/backward side button for web browsing

It has awesome buttons, great glide, and perfect response time for my daily Photoshop, email, coding work

They changed it, quality is much lower, it missing the thumb button and the mouse quit working after one day.

The top buttons are a little flimsy, but otherwise work perfectly fine.

The top buttons are a little flimsy, but otherwise work perfectly fine.

Not recommended for game use as the buttons will stop working

Effective wireless that "just works", nice, comfortable design, and forward and back buttons on the side

The button on the thumb rest is unique and very much appreciated too!I did have to return and get a new one because the tilt scrolling was too sensitive, and I *STILL* feel it's a bit too sensitive

Middle button broke after 1.5 month

Also the buttons are very unpredictable

I think this problem is exacerbated by the wonderful shape of the mouse which naturally concentrates a bit more of your hand weight on the right button.

Very comfortable to use, very good scroll wheel, and love the back/forward buttons on the side.

very ergonomic, good responsiveness, has some useful buttons in places where they're easy to use

The buttons are stiff and difficult to press, and trying to use the scroll wheel button as a double click makes the mouse pointer move because it's so resistant to being pressed

I hate the lock/unlock wheel button, who wants a free-spinning scroll, people who don't understand the page up/down keys

The buttons are nice, scroll wheel is great and scrolling options are good, even though I rarely switch between them

and I really like all the extra buttons

The left and right click buttons are extremely close to each other and angle slightly so that if you are pressing the right click button it will slide to the left and under the left click button preventing both buttons from being pressed

If you do like those buttons then great
