Had this one for like three years and I love that you can adjust the position of the side buttons to your liking. Only shame is the known issue about the scroll wheel being ass and the encoder eventually throwing in the towel if you click it a lot, which I do. Managed to get it working again by disassembling it and putting it back together, but I'll eventually have to look for an alternative.
Even if I don't play them anymore, I'll definitively stick to an mmo mouse for the convenience.
