This is a $20 shelf set at most. 

Pros:
It looks nice
It was easy to install

Cons:
The double sided sticky tape they provide to stick the template to the wall is super enjoyable to peel off your wall. Especially when it disintegrates into powder and leaves the sticky residue on the walls.
The hollow wall anchors that come with it are useless and spin in any size hole you drill. Get some screw-in zinc ones for drywall and you should be ok.
The edges of the melamine on the shelves is all chipped up so it's a mixture of gray and brown you can see showing through. 
Lastly, the shelves don't sit perfectly flat and are able to be tilted up or down. Be careful if you put anything that might spill on them.
