This thing is a piece of junk. Major flaws:
1. made from sheet metal. The top ends are bent and there are air gaps around the bends. No welding or finishing.
2. Screws to hold frame together are plainly visible
3. Shelves do not fit flush to wall. If you use the pre drilled holes, there is a gap of 5.5" between the botom shelf and the wall.

For the $4 of raw material in this, more quality is needed to justify the price.
