I really liked mine (no longer have it). It had a good feel, plus the lighting was pretty sweet for LAN parties (I used it with my modded LAN party rig at the time). It wasn't "perfect" though, because IMO the fatal flaw was that the knob on the keyboard controlled a dimmer for the lights while buttons controlled the multimedia volume. I would have rather the knob control volume because that would be more intuitive for me, plus the lights aren't very bright so almost no point in dimming them.
Still, I'd buy another one, but it is OOS now.
