Got about three years of use before I switched to a TKL format keyboard. The G-Keys were great when I used macros more frequently, but circumstances changed and I no longer use macros as often. I've tested each key and they all work. That said, the F7 key has a tendency to be a little stiff, but doesn't require much extra force to push down. While you can use the included wrist rest, I'd recommend buying a new one (I use a HyperX TKL one; memory foam does wonders imo.)
