Got it for a great price, excellent mouse with amazing software. RGB is brilliant and AIMO works well. Only reason not to buy this mouse is that it's brother, the Kone, is also very well priced.
I put this as "not comfortable" for personal reasons, if you have medium to large hands.. maybe large hands is preferable this is an endgame palm mouse
Clicks are nice, sensor is nice, no problems with the coating.
So buy without worries if you are a palm user with decent sized hands!
