mainly is calibration issues. Have lot problem after calibrations. Also it's cursor also stop moving totally from 3 days before. Still not moving. Razer products are costliest among every top gaming peripheral's company. If these kind of problems occurs continuously, then many will turn on other companies. :\

Has a lot of calibration issues. The mouse starts misbehaving once in a while and I have to recalibrate it. Once I do that, the mouse handles a bit differently than before. The change is slight but has a humongous effect on my gaming. In games like cs go where precision is prime, this is a strict no no. Can't believe this happens after I pay 5k for this. Just aas I heard razer products suck.

I have been using Razer's mouses for few years. This is actually my third Razer's mouse. I used Mamba and deathadder before. This is by far the best one i have owned. It's shape and materials use in this mouse is very good. The lighting effects is a big plus. So far i have not see any problem with this mouse. It's basically plug and play. I will definately get the wireless version of this mouse once it comes out.

The best mouse out there. The feel and sensitivity is mind blowing. Do the samba with the mamba!

Pitch!!!! its Razer, there is no need to say anything
