Cute and stylish
Color: Oak, Size: 24W x 11.6D x 2H, 2 Pack, Color: Oak, Size: 24W x 11.6D x 2H, 2 Pack
The shelves look super cute in my laundry closet redesign. Not heavy duty, but that’s okay for my purposes.

Shelf is nice, bracing is garbage.
Color: Black, Size: 35.6W x 11.6D x 2H, 2 Pack
Just like all the other reviews, it sags. Regardless of how its mounted to the wall, the bracing itself is weak. Shelf is nice though, definitely would have to get different brackets to make this worth it.

Decent shelf
Color: Walnut, Size: 35.6W x 11.6D x 2H, 2 Pack, Color: Walnut, Size: 35.6W x 11.6D x 2H, 2 Pack
They look great and come exactly as described. They were super easy to install and came with everything you need. Sizing is exactly as described. For the price they’re all around a great purchase. I bought these to mount under our tv for video game consoles and they are perfect.
However, they do not sit well on the wall. There’s only two mounting points when they should definitely have 3. We had to go get a shelf bracket from lowe’s to get it to sit right and not lean forward. So just beware if you want it to sit flush, you’re going to need something additional. Still worth it for the price!

Thanks to Amazon
Color: White, Size: 35.6W x 11.6D x 2H, 2 Pack
Well, one thing I have to say is we got one white shelf and one brown shelf and it did look like the box had been opened. But that being said Amazon was very wonderful and told us to keep it took it off my bill. They didn’t even charge me for it. The assembly was super easy. My husband said it was very easy to install. All he did was paint the brown and white and put it on the wall so we lucked out on that one thank you

Works well with new hardware.
Color: White, Size: 24W x 11.6D x 2H, 2 Pack
The product is good and strong if you install the bracket securely to the wall. Do not use the supplied fasteners for sheet rock. Buy new fasteners at Home Depot that clamp tightly to the sheet rock and everything will be fine.
