I am really happy with the quality of all parts, couple small items were missing (the screw head caps & one hex key. The installation instructions are really poor. I am not a professional installer, did this the first time. No mention of moving the sliding door stopper closer to the wall in order to allow maximum opening of the sliding door. No detail provided on how the small glass should stack up on the fixed side glass. These are minor details that help a non professional installer.
