there is a 3/8 inches chip on the top front edge, that is not visible in picture, probably one that was not the one in the picture, and when 1st powered on the o key did not work at all, so much for being checked right the 1st ones we ordered were very good, this one not as good as the others. our customer decided to see if the o key would keep working, after our effort to free it up seemed to be working. Lesson learned will completely check from now on before we deliver to our buyer
