So what about G600 firmware? Is it still not flashable or new units get the newest firmware and its flashable? A lot of ppl having mouse movement issues and mouse pointer delay problems, the g-shift button migth be nice, but some ppl say it's hard to press other say its the same as left and right and u might miss click it, also it's mutch wigder because of it and is the 12 button grid easy to press? Is it hard to reach 10 11 12 buttons? I had original Nagal for like a 2year now and I use all the 12 button when i play, so its very important to me.
