Pros: big mouse, high sensitivity, flexibility in buttons and colors
Cons: mouse architecture
Razer Naga is one of the best MMO mice and the high number of copies sold upholds its position, but the drawback is that the last buttons on side 7,8,9 and especially 10,11,12 are really hard to press and if you play a game for hours using those buttons your fingers hurt. I would have been smarter to make only 9 or create a better feel of the buttons together with re-positioning them in a more frontal position.
The size also bothers me a bit. I really wish it fit in my hand the way the Deathadder does.
