Been using this for more than 3 years now, light weight easyly portable mouse. Tested the range of this mouse and it worked from more than 10 meters.Response time is good so easy for gaming.It takes only one battery and works for many days without issue.
Its also very robust and the buttons are flexible so they dont get loose over long usage.It was Rs.1000 when I bought it, must be less now, its worth it.Overall a good product for the price, go for it.!
