Decent product, you get what you pay for
Easy to put together and good price, fit the space we had perfectly. Cheap material, but you shouldn't be surprised considering the price. I saw another review commenting on the difficulty lining up the nails for the back. Wish I would have read it before the assembly as the nails popped through the front side and I had to knock them back and repaint the spots. The directions don't state which size drill bit to use for the wall anchors, but 5/16" worked well. Overall, not great but not terrible either.

Just right
Very easy to assemble, the way it is secured to the wall was good. The only thing was the nails on the back did not match with the back board and the side boards. The amount of space is just right.
