I bought this from some other store. It's been more than six months I've been using this mouse. It is excellent but it prefers better surface, you'll need a good mousepad. Also the click kinda gets problem after two pr three months of use. There is a double clicking problem when you single click. I think it is a problem with almost all Razer products.
It is still an excellent mouse. I'm using it and will use it in the future. Is is very sensitive. Good for almost all type of games. And the s...

6400 dpi make's it a beast. But of course you don't need that much.
Overall it's a great mouse for Palm grip.
According to Razer, it is designed for razer scarab and vice-versa, so am using it with Scarab.
Problem with this mouse is that the mouse freezes on lift off when you are playing @1000Hz with Surface Calibration On.
Razer Synapse make's it loaded.
I wish razer would have provided with multiple Lighting colors.

This mouse just dont work. some times the mouse pointer starts flickering. I tried keeping in different surfaces but it refuse to work properly. I also bought a steel series mice pad so that there is will work. But the mouse absolutely does not work there. Only option I have now is to dump it and buy another. Waste of 3000 rs

As Razer says, it is true! This is the most ergonomic mouse ever!
I found it to be more ergonomic than Razer Taipan!
You can easily sit for long sessions of gaming without any hand fatigue and you will never regret spending your money on this piece of equipment.
Don't think, just buy this mouse and start fragging!

This is not a great mouse, sometimes for 1/2 a second the mouse won't respond. DPI switch and the custom settings is good, but the freezing is really an issue, tried various polling options, not helping much. Erogonomics is OK. Compared to Microsoft precision mouse this product is not recommended. I wanted this as an upgrade to MS Precision mouse, but then I am still retaining that.
