Modular Seat Headrest

So the screw holes are all of a slightly smaller size then needed. I needed to revore them to fet the screws to fit. And speaking of the screws, they have the shallowest hole for the alan wrench ive ever seen. The wrench would slip out of my hands at leaat once per three revolutions. One screw just would not go in and uptimately snapped the tool. I finally got it together with my own hardware and some extra work that I shouldnt have had to do. The only reason that my rating isnt lower is vecause, after all the qork and my own screws and alan wrench, its pretty solid. Dont know if Id buy another but it is what it is.
