Should i buy old razer mouse

Solution
If you like using it plugged in, then go for it. That battery on that model doesn't have the best life span (one of the reasons I ditched it) and will cost more than the mouse to replace. If you're in a hot climate the glue holding the thumb pad on to the body likes to melt over time as well (reason two I ditched the mouse). I will say this for Razer, their tech support people are very nice. I got to talk to them a lot while I owned that mouse.
