it's an inexpensive mouse. One position on the scroll wheel causes the screen to jitter up and down, but besides that, it gets the job done.

[This review was collected as part of a promotion.] I'm a python developer and like to game casually on the side. The M300 it fully satisfies my expectations, from CS:GO to Starcraft II.This mouse fits well in my hand. I'm often in palm grip, trying to do more claw grip lately and this mouse serves me well in both styles. It might be too big for a claw-grip only gamer. The buttons on the opposite side of the thumb do get pressed without me wanting to, but I don't have anything assigned there, so beware if you need these extra two buttons! I had a Razer BlackAdder previously and the transition was almost non existent. All in all, very nice performance mouse!
