The quality is good, but note that 3 of the 5 shelves are NOT adjustable!  The bottom, middle, and top shelves screw into the frame in the exact positions that you see in the picture...these 3 shelves are actually made differently than the other 2 shelves and cannot be interchanged.  The 2 adjustable shelves rest on top of pins that you can set at any of 3 different heights BETWEEN the non-adjustable shelves.  I ended up just not screwing in the bottom shelf and skipping an adjustable shelf and luckily it still worked for me, but it could have been a deal breaker.
