Nice product, wall mounting could be easier
Size: 7.9"D x 39.4"W x 34.3"H, Color: White
Easy to put together, nice finish. Missing a star cause mounting it to the wall is a lil more difficult than it should be. I would never use the wall anchors to mount this

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.

Looks amazing! Perfect Gift
Solid shelves however the instructions were really difficult to follow even with three people helping. Looks absolutely amazing so it deserves 5 stars.
