I woke up one night to a crash of something hitting the floor somewhere in my two-floor house.  So, I got out of bed to explore-"what now?"  I didn't go far from my first floor bedrm thru my bathroom into my walk-in closet to discover one entire side (52") of it's original plastic shelving had pulled out of the wall and everything hanging was laying on the floor.  I couldn't quite understand since the weight hadn't changed over time, but I decided to order what I hope is a "better quality unit" (although I only intend to install the 52" unit and hold off on the 32" unit at this time).  I hired my Handyman to install the unit in wall studs so I feel confident this one is gonna stay-so far/so good.  Arrived in good time and good shape, all parts as expected!
