Love it 😊
Size: 7.9"D x 39.4"W x 34.3"H, Color: Brown
This is an amazing product, It holds quite a bit, very durable and I havent had any trouble with it besides the led lights that are on the top wont stick. Other than that, its very easy to use and can hold alot of weight.

The hardware to hold the shelves doesn’t hold good enough
Color: Batteries Powered
The shelves look great , the only thing was the wall fasteners were too big for the screws and it doesn’t lock the screws in place tight enough to hold the shelve in the wall
