Not too light, not too hard to click and extremely responsive.-Sensor is the best I've ever used, works great at 1000hz.-This mouse with 1 weight at the back without the cover on the bottom on a Razer Goliath mouse pad is the most accurate mouse I have ever used to date

The optical sensor is a notable change from the laser I was using, and I frankly like everything about this mouse

scrollingI still love it, sensor is solid, mouse click is VERY precisevery good mouse!excellent price performance, feels like a 99+ mousePRO:the solid metal mousewheel feels like qualityleft click and right click are very crisp, precise, and bouncyshape is not perfect but goodsensor is working

The sensor is very precise, and the experience of moving the pointer around feels buttery smooth

A "flawless" sensor and a ton of buttons makes this my favorite mouse I've owned

The sensor is fantastic and the buttons click just

Excellent tracking sensor a tad slow on response so slower hand movements like aiming on a FPS game is harder for pinpoint accuracy

that.the sensor and the quality of the buttons is superb on this mouse.

the sensor is very good but this mouse is heavy for me

Good quality optical sensor gives really good precision that's not just digital/software based

Optical sensor is accurate for almost any FPS game out in 2018

I ended up successfully replacing the switches in that mouse, but in the process scratched up the sensor, so it was bricked anyway

The sensor is AMAZING

It has a shape ergonomically-sound for all palm/fingertip/claw-grippers alike, the sensor is flawless, its software is lightweight, and the programmable-buttons are intuitively placed for a multitude of quickly accessible binds that wont be accidentally triggered (yes, you can reassign the DPI button to provide a different function/keystroke)

The sensor is fantastic and the software works quite well

Excellent 3366 sensor, low LOD

This mouse is so Awesome, I previously had a $6 dollar gaming mouse with bad clicks and scrolling wheel and a really bad Laser Sensor

The sensor is fantastic and the software works quite well

Good button placementGood scroll wheel, infinite and regularGreat sensor, no issuesEasy software controlCons:VERY VERY heavy, 120g without weights, already much greater than other esports mice, if you're playing FPS don't buy this mouse, there are more simple

The sensor is extremely accurate and reliable (as I've come to expect from Logitech mice)

I picked up this mouse because it has a flawless sensor and has a good amount of side buttons

The sensor is every bit as good as they say at 200dpi to the only-used-as-a-joke 12,000dpi

The sensor in this thing is very accurate

Sensor is great on most mouse pads

Coming from razer products,this is probably the best mouse i've used, I love heavy mice and the sensor is just excellent.

The sensor is great, the shape and design are very good

The sensor is amazing

The mouse comes with 5 3.5kg interswappable weights, and a sexy case to store them in.-Extremely accurate sensor

The best mouse I've ever ownedIt hast a lot of buttons and works greatA nice sensor and confortable grip

It has amazing build quality, an amazing sensor, and amazing buttons

I've ever used with one of the best sensors ever

Sensor, this sensor was introduced in 2014 with the Proteus Core, and is still one of the best sensors on the market to this day

Great sensor and shape

This is honestly a really great mouse it has up to 12,000 dpi and the Optical sensor 👌

It worked great, the sensor was so much better for FPS

It worked great, the sensor was so much better for FPS

After two years of owning the G502 I decided to go for something different and tried Razer's Deathadder Elite, and even though the Deathadder Elite has a slightly superior sensor (at least on paper) and weighs less, I could never get used to it

Great ergonomic mouse, clicks are amazing, and sensor is really precise.

And this is arguably one of the best sensors on the market

Very good sensor

If you need a gaming mouse with a good sensor and a good number of programable buttons (including tilting the scroll wheel to the left and to the right!) and a really cool scroll wheel that has two modes, regular good ol' scroll wheel mode and SWOOSH INFINITE SPIN mode, this is a really really cool mouse with a solid price.

Excellent tracking sensor a tad slow on response so slower hand movements like aiming on a FPS game is harder for pinpoint accuracy

The best sensor to FPS

the sensor is incredibly accurate and of high quality- the grip material is

The sensor is perfect and the scroll wheel is pretty close to perfect with the best of both worlds scroll toggle

Sensor can be a bit jumpy but that is potentially due to the surface I use it on

Best sensor on the market, the consistency is unmatched by any other mouse I have used.

Works great, excellent sensor and tracking, programmable buttons have lots of options

Great sensor and great mouse for shooters

No sensor rattle however ALL the buttons rattle so it's a loud mouse.

Mouse worked well for about 4 months, now the sensor seems to be malfunctioning

The sensor is perfect on my Corsair gaming mat, the weights make the mouse feel amazing in my hand (I use all 5), and the ergonomic shape is great for my grip

Great sensor, great mouse.

Great sensor and grips.

The sensor is so perfect that I know I can rely on my aim and the mouse won't mess it up

The sensor, I believe, is the best you can get at the moment!Only flaws are the nylon cable (makes it harder to organize) and when middle clicking I sometimes click it the wrong way which makes it go left or right (due to the aforementioned "arrow key" feature)

However, the sensor is a real problem

Pros:-Adaptable sensor

The sensor is one of the best, with a PMW3366, this as no problems with tracking

Best sensor best mouse period.

I expected more because of all the good reviews and good sensor used, but the physical characteristics of the mouse are pretty bad

Feels great in the hands, the sensor is super accurate, and all buttons respond really well

and it feels that at some point i will click it and it will just break, the sensor was good and very responsive with no tracking issues

It has plenty of buttons, an amazing sensor with 1 to 1 tracking (I tested it), and an option to switch between a free moving scroll wheel and a normal one

The sensor on this mouse is honestly amazing, that's why its so high up in my favorite's

Sensor has been very accurate so far, and the cable is

Couple that with a really awesome sensor that is super accurate and sensitive to slightest movements and tracks on any surface (seriously I tried everything from a white paper to the palm of my hand) and you have a potential winner

The sensor is also really great and smooth, making use of every frame that your game can dish out

Felt an immediate improvement in my aim (maybe a better sensor + better
