i have/use one for over a year now its holding up well. good battery life, somewhat lightweight (69 grams)
one of the top budget mice for sure
my only gripe is that unplugging or plugging in the wire while riot client is open will freeze the mouse until you revert what you just did
my first "gaming" mouse was steelseries rival 600 (96g) and I felt a big difference switching to model o. however, you'll get used to it. I cant see my self using any heavier mice now
