For the price, this is a decent product however:
* The metal mounts are wonky at best. It feels hand made, but not in a good way.
* The base parts of the mounts, where the holes for the screws are placed, don't line up with each other, and I had to bend the whole thing to put it flat against the wall.
* There is no way to affix the shelves to the metal mounts. They just float. One could drill holes into the mounts and screw in the shelves, but this seems to me like an egregious oversight.
* No hardware for hanging this thing was included (anchors screws etc).
* It comes with no instructions, no information at all. Just three pieces of wood - cheap but stained consistently, and two metal monstrosities.

In conclusion, only buy this if you are extremely handy and on a budget. The end result looks good, but will require some extra effort and elbow grease.
