Hi all.. i bought a DeathAdder last year together with eXactMat.. DeathAdder is simply a big & heavy mouse.. so users have to use a palm grip instead but my hand was kinda small so i have to use fingertip grip to move the mouse around & disadvantage is my hand get very tired easily.. & was kinda regret when the eXactMat caused minor scratches to my mouse feet & my mouse tends to slow down so i wouldn't recommend eXactMat to the rest if you want your mouse to be in good condition but would rather recommend if you want it for durability since it's made of aluminum.. so i bought a copperhead with a free Mantis at IT fair.. & now i'm using the mantis speed as my mouse pad instead of control version although i am a hardcore RTS Warcraft III ladder gamer.. glad to say that it's very smooth when i am still using the DeathAdder.. so it's still best to refer to the ergonomics guide before buying a suitable razer mouse.. if your hand is small to medium, i would either recommend copperhead or diamondback..
Below is a guide from Razer for those who are not sure which Razer mouse suits them
