I had this one and another one that I borrowed from a friend for a while. I forgot which model it was. It just felt...awkward. I like the ergonomics of Logitechs and Microsoft mice better (despite some of their ugly lettering on the mice).which one did you have, I have a Mamba (the orochi's big brother) which is also wired & wireless and I love it, it's comfortable, the buttons are nice and it tracks so well
Check out the Logitech G500. Works extremely well (and great customer support).
This one looks interesting. However, I'm not looking for a "gaming" mouse.
