Optical MMO/FPS, up to 4K dpi, max 1000Hz polling rate, avago sensor, omron switches, 13 buttons, internal memory to save profiles, weight tuning set, good tracking, teflon feet.
I have this mouse and I been using it for almost a month now. It took a while until I got used to, but now I can't game without it. Also, the software it is not very intuitive, but it is usable and once you get used it will work just fine. I play war thunder (mmo) and I feel like I need 2 extra buttons compared to a regular 5 buttons mouse (I do not count the dpi+- buttons). This may sound strange, but before this mouse I returned a G502. I also have the G302 sitting on my desk besides this one, still I like to game with Z-7900.
This mouse looks like a copy of Redragon M902 except it is optical (vs laser) and only 4K dpi vs 16400 on M902, but other than this (and color) they look alike.
gives this mouse an A.
Usually the price is around $24, but at $16 I would say this is a steal!
