Have been using a broken Habu, but have just re-wired the usb cable and now no more connection issues
Using a Razer DeathAdder 1800DPI mouse here at the moment, have ordered the Razer DeathAdder Respawned 3500dpi one however. :]
It's useless. I use mine at 900DPI because anything higher is unusable in several games (CS can't go bellow 1 of sensitivity and it's still wayyyyyy too fast)
A4 TECH wireless set, RBW-5 mouse. Good enough for me but I know you real gamers out there will scoff at my choice. Hell, I only paid £20 for the set as it was ex-display in a local shop. ^_^'
I use a G500 with the max weight in it. Been used to a bluetooth mx1000 mouse with battery and so far I am rediscovering the joy of wired hardwire. No more dropped connections or battery death ect!
