I'd give 4 1/2 if there was one. The shelves thwmself are nice I just don't like the visible little black set screws. The shelves themself look great and are not wobbly at all if you install correctly. I purposely installed the bracket upside down because of the little black setting screws; I didnt want them showing because the shelves are above eye level and the screws are black and I didn't want them showing. But that made the shelf lean amd wobbly so I turned them back over the way they are supposed to be and that made them level and sturdy. I guess I'll paint the little screws.

Beautiful & functional

Size: 24x7.9, Color: Black

I was really surprised at how easy these shelves were to install. They look great, and give an elegant, subtle, look to any room. I'm using them in my home office. I plan to order a couple more sets soon.

Great small hanging shelf

These were a great addition to my DYI bathroom remodel. I needed that exact length and it fit perfect for my needs and I was able to install it myself. I’m a 53-year-old woman. I used the other one for a shelf for a candle as well. It holds my oral hygiene caddy well, keeping my sink counter clean.
