Great product that's easy to install and frees up space on your desk.
Style: Deluxe
Easy to install. Nice quality product with good directions. Five out of five stars.
Note that if you're going to mount a laptop, and cables will be running to it, make sure that the mount's vertical support features don't interfere with where your connector locations are on the laptop. I got lucky, ha.

Cute and stylish

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!
