Just installed, so we'll see how well it lasts. As one reviewer stated, the installation instructions are in one of the description photos. What wasn't immediately clear to me was, when attaching the mounting brackets to the wall, don't drill the holes on a horizontal alignment. If you do, it makes getting at the screws with a screwdriver challenging.
i also opted to use 1/8" toggle bolts where I had no stud behind the drywall. Everything seems fairly solid mounted this way.
