NOTES FROM THE SELLER ITEM ULTRA RARE Art Lebedev Optimus Maximus keyboard black - OLED WORKS BUT READ!! ITEM CONDITION: WORKING WITH ISSUES - SEE PICTURES AND VIDEO. found in an estate in the bag, the keys look new, no noticed scratches. upon testing, everything appeared excellent at first with normal keys, however when I threw a all white background on it, I noticed that 4 of the keys are a little darker, and the right windows key does not display and does not work. I did not attempt to do anything to it as its ultra rare and high priced. Maybe you can simply re-insert the key to fix it but im not sure. Guaranteed to work as I describe it.
