WELCOME
Some months ago I bought the cheapest mouse on amazon with the sensor PIXART PMW-3360 Optical, a great sensor to can track your movements. I wanted it because I like play shooter games, and with my old mouse is a little difficult.
The grip is good (not as good as other mouses, but it's okay for the price), It's heavy enough for me, and it has 3 RGB zones, so the mouse looks good. The material is hard, the only thing that I feel a little 'cheap' is the side buttons, I don't like them a lot (I don't use side buttons btw).
The great thing about this mouse, is that it track so good my movements, fast and perfectly, I can do fast movements to shot a character in the face without any problem.
The software it's okay, it has good features to can customize your mouse and you can save profiles in the mouse itself.
So I think it's a good pucharse with this price, you get a good branded mouse (there's other options at this price, but not with good brands) with a great sensor!
If you want to ask me something about the mouse, go to the comments, i'm going to answer you quickly!
