Packaging is a mess and product requires force to put parts together
Color: Black
Packaging is awful, makes a complete mess. The product itself is okay, the little rods that come with it don't slide in easily and force you to scrape the metal with them when you install it , not the greatest design. Instructions also are not the best. Also, why are the holes to hang the shelf at the bottom?? Doesn't make much sense

Do not buy. Object is falsely advertised bigger than it is.
Color: Rustic Brown + Black
Deserves zero stars. Bought for my kid's birthday to mount PS5 on the wall like in the picture of the product. False advertising. Deception.

Excellent accent for a wall in your home
Color: Black
Oh Wow!!! My wall looks sooo good. Love that it has shelves on it. A perfect wall accent and just the right size. I have it on a corner wall and have never banged into it. Well worth the money and definitely well made. Heavy so plan to anchor.
