The quality is high and assembly easy.  Wheels on doors are same height  as depth of track which means they do not roll.  Had to rip a 1/4" by 29" piece of packing material hardboard 1/16" thick and insert in track so wheel frame would clear the track.  It rolls beautifully now and looks great in our great room.

Pros: Great looking, easy assembly
Cons: Wheel height and track depth makes it unusable without a simple modification.
