The shelving unit was not as I had expected. It arrived damaged. The damage is on the under side though. They are hollow and not hardwood as I had expected. Save your money if you want something of good quality. These are like 3 pieces of pressed wood glued together. They are space saving and look great in my space. The mounting hardware it comes with was plenty enough to hang these but make sure you hang them in the studs if at all possible. Assembly was simple. It does come with a micro level. Which a kid or pet could accidentally swallow. It’s like pill capsule sized so just be careful when opening the package.

Very well made and solid. All the parts fit together perfectly. Very convenient you can plug in a lamp and charge your phone with the usb ports. Great value for the money.

Perfect

These are the perfect size. A little long cumbersome putting them together. They look very nice for a small nightstand
