Pros: This is my third gaming mouse, the last one being a logitech g9x. I've spent alot of time going through reviews of different models in an effort to find the perfect mouse. The sensor is great, and the mouse is quite comfortable. The middle button clicks in easily. The side buttons give a responsive click. Drivers haven't given me any problems. Was worried it wouldn't let me claw grip at first, but it does- you can hold it either way.

Cons: This mouse is terrible with sweat. You might not realize you have sweaty hands until you try this. I've always known my hands sweat a tiny bit, but the coating on this just makes it so obvious, it's always wet. I'm sure this will cause wear, if the mouse doesn't die first (i hear razer products don't last long, we'll see) Logo on the mouse can either be turned off, or "on" mode which constantly turns on and off every 2 seconds. WHY someone would design this knowing MOST PEOPLE DONT WANT THIS, is beyond me. Ive learned to live with it on "pulsing" but it's still distracting and you'll find yourself pushing it out of the way or turning it off when you're watching something.

Overall Review: Turned off "surface calibration" because its a gimmick. Tried using it at first but my mouse was occasionally flying off-screen. Tried it with the 2 very popular pads ripper and steelseries qck, works better with it off. Apparently it's only to decrease lift-off distance anyways, which it didn't do (and you can manually change) Very light. As someone mentioned, makes it feel a bit cheap, especially coming from the heavier logitech g9x with an additional anti-sweat grip. But don't get me wrong, that logitech had 2 important buttons stop responding and the middle button is a joke. Still haven't found the "perfect mouse" but so far this is the closest one

Pros: Changeable grips and weights though i should mention i've only ever used the textured "claw" grip, the other one gets way too sweaty. And i've only left default weights in there, i don't really care. Things like the censor and actual working buttons are far more important when it comes to finding a decent mouse.

Cons: Honestly should've listened to the lower reviews. 2 buttons stopped working, 1 side button and 1 DPI button. Middle button is garbage from the beginning, then actually broke on me. Again, i wish i'd listened to the reviews. Way too hard to click, and you'll never use the "push scroll wheel left or right" buttons because they are hard to push in, and one is way easier than the other causing accidental button hits so i've always kept them off. After a year or so, the scrolling tactile just stopped responding properly. So with dpi buttons not responding and 1 side button not working, and the scrolling being already hard but now unusable, i seriously recommend you look into something else. Maybe a different series, personally i'm done with logitech products.

Overall Review: Precision is listed as "decent" on many review sites. For this price you can find something much better than this, unless you actually care about changing the weight.

Pros: I'm happy- it's a great pad. Way bigger than i expected, it's on my keyboard tray and i'm using about 40% of it. I want to point out that because it's nice and smooth i'm really not getting cat hair in it much. My old steelseries pad was a nightmare compared to this.

Cons: The logo is honestly bigger than i'd like it to be.

Overall Review: It didn't even take 2 hours for the smell to go away.
