well in general , work great i have use it in LOTR Online , Diablo III , Minecraft , the one and only problem i have be that my spacebar look like it be only light from one side , so the etched bar that run across the space bar run from bright red on the right side to very dim red on the left , also the evenne of the lighting through various key be off , in particular with the back light on high my b , v , a , z , and right ctrl key look brighter than the rest . it be a little annoying but only noticeable in the dark .
