I purchased my Z10 keyboard a while back when they were doing the Torq mouse keyboard combo. I love the mechanical keyboard, however the volume slider and the LED screen need improvement. The volume slider has a mind of it's own, I try to turn it up or down and with the first tries nothing happens, then the volume will suddenly jump all the way up or stop at 10 and then stay there until I wiggle it more, really disappointed in that aspect. Then the other day I contacted customer support about the volume slider, they had me update the firmware and the Z10 software, now the LED screen has quit working all together! My entire computer is built with EVGA products, I will be replacing my EVGA Z10 keyboard with a competitors keyboard, I don't want to but I'm left little option. This is my second Z10 first one was DOA!
