me either, so i sell all my razer eq... but is worth to use for surfing due long warranty period...

i feel the different every time i click the + / - button lols
but my when friend using it they say still same fast cannot control 

maybe the mouse really got a lot prob they don realise it when they build this mouse, sometime they tested okay but once it selling out problems occur,

don forget malaysia stil tax for the mouse X8.. but price wont different much actually..

Not sure. Depends on the price.
Definitely the Razer Mamba as a demo set. Thousands of hands will swarm the mouse just like the previous Lycosa Mirror on the fair.
