Overall good quality & sturdy, only a couple minor issues.
Rack seems well engineered, but has minor issues:  1) One side of one the wheels came loose within 2 minutes of attaching & doesn’t seem to want to stay on.  I don’t really want to go through the hassle of sending the whole thing back just because of that however, and I’ll just pass by the home supply store (or contact the vendor) to see if I can get a replacement. 2) The hangers don’t really hold onto laminated charts well (they kept sliding off), but I fixed that by adding a little tape to help reinforce them.  The hangers look nice though & I will experiment with Velcro, other clamps, etc. to see what else will work.  Other than these two relatively minor issues, the rack is great & looks nice in my classroom.  Assembly was REALLY EASY - just follow the directions.
