Hey - turns out IRC is out and something a little more modern has taken it's place... A little thing called Discord!

Switched from 510 to 518 a few years back, very similar mice, probably the preferred option if u cba to spend much or to get used to a different shape.
If I were to buy a mouse now I'd probably go for the G5 or the Steelseries Ikari, which is meant to be good aswell.
recently just changed to the Steelseries Ikari optical version, really good mouse I like it. I had an MS optical before but found it kept cutting out while i was playing, dont have this problem with the ikari tho!
