I have a cheap Logitech M185 wireless mouse which I use it for work, even though I have a Force Touch pad... Try playing FPS with Touch Pad. Anyway, due to how I treat the mouse (dropping it rather often), one of the feet fell off, which makes gliding extremely rough. So after searching Google for replacement, there's a rather affordable and good replacement feet called Hotline Gaming mouse feet, even for the cheapo M185. The difference is pretty dramatic, even if your existing feet are still fine. There are 2 choices of thickness, 2.8mm or 6mm. 6mm can replace the old feet, while 2.8mm is usually for sticking on top of the existing ones. I might get one set for my G400.
