Summary: I bought this mouse after two years of using the Razer Naga. I decided to switch because I have large hands and the Naga never really was very comfortable for me to hold. That said, the size of this mouse may be the only thing I like about it. The membrane thumb panel buttons feel mushy and gross and you have to have your finger in a very specific spot in order for the 3rd mouse button to click properly.
Summary: The mouse seems great, I had such high hopes and I wanted it to work, but it just has one major problem. The mouse will jump up or down whenever playing a game, the issue can happen anywhere and makes playing with it very frustrating. This issue is well know and there has yet to be any fix yet.
Excerpt: PROS: Great product easily the best mouse i've ever had.Very resopnsive, feels great in my hand and very east to distinguish each button, tons of buttons, speeds, and profile options.Also has easy to use software CONS: (HAD TO SEND IT BACK BECAUSE ONE OF THE G-BUTTONS DIDNT WORK, STILL WAITING FOR THE NEW ONE TO GET HERE) the g-shift button takes a while to get use to and is extremly to easy to press they should have made it where it would take a little effort to press,...
Pros: Accurate Tracking, Comfortable Design, Fast Response, Glides Smoothly, Great Features
Summary: First, I will say that I absolutely love Logitech products. I've been gaming with their mice for years, going from an MX to a G9X to a G700 and, at least temporarily, to this G600. There is absolutely, positively nothing wrong with the mouse from a quality perspective. Absolutely top-notch and a very nice weight. (I tend to like heavier mice.) That said, the mouse is simply too wide for me.
