I used Logitech for 3 years,no issue and Battery I forgot when last time I installed Duracell. Yes DPI is concern with Wireless but good quality laser can be handy for gaming also. wanna try this one...good and comfortable design.

Very laggy. Has no precision whatsoever. I end up trying two n three times to just hit normal buttons while surfing. It lags even when I move it around slowly. This is my first wireless mouse, so I dont know if this is how they're supposed to react....
