this is so sturdy and high quality.  However you will be deceived as to how easy it is to install.  The instructions are 1 photo, so I thought I was missing something and pondered for 30 minutes before I screwed the "dodads" into the predrilled holes, set the box (they call it drawer) down, and pushed it shut, and everything connected on its own...still can't figure how, but it works great.
