I love these shelves (I purchased 6 shelves total). The size I got was perfect, looks phenomenal, & quality is great too! Only negative thing I’d say is that it could be difficult for some people to set up as it needs to be leveled, & can be hard to align with other things since the part that attaches to the wall is separate from the shelf (due to its floating design) but once it’s up, it looks great. Definitely good value for money with its quality. I have them to hold up decorations/toys, & you think some of my shelves have about 5lbs of stuff on it & I’ve had no issues, so functionality is good.

Extremely satisfied

Very nice. I am extremely happy with them. I used painters tape to hold the bracket in place while I screwed it in, worked like a charm 😁 holds a lot of items

Good enough

Size: 15x6.8, Color: Black

As cheap as the day is long but functional. These are basically made out of highly compressed paper and finished to feel like wood. The first one I put up was good with a little tilt to the back which is fine. The second one has a more severe tilt and I had to bend the bracket down to decently level it out. They are sturdy enough to hold quite a bit of weight and look good for what they are. I'm not impressed but I'm also not disappointed, the price is a bit steep for what they are but they serve their purpose.

Great, but bring your own inserts.

Size: 24x7.9, Color: Black

These work great, easy to install. Happy with them. Only problem was the instructions say don’t use the include inserts on wallboard, which meant I had to go out and purchase my own. That’s OK, because I like to use inserts I trust.
