It's a comfortable mouse but the adhesive for the thumb grip lost its's stick after about 5 months of use

Only thing that I didn't like was the notorious issue with this mouses' wheel click function button getting stuck and not working properly.

Cheap stick on side thumb pad falls off

The switches all feel good, if I had to nitpick I'd like a scroll wheel with more stiff scroll steps

if it breaks i just call razer and give them its info and theyll replace it

you want high accuracy and play mostly fps like cs go or rainbow six, zowie is the better one and you can actually feel that you are aiming better with the best sensor

The scroll wheel feels fine, the software to change the dpi is awesome, the thumb buttons are in a pretty ideal location, and the clicking is great, but for some reason, since this is ergonomic, it felt small... and for that reason it never felt comfortable playing cs:go, which is a game i've been playing now for over 15 years.
