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.

Did its job for moderate weight items.

Size: 40 Inch, Color: Black, Number of Items: 1

Easy install, a little expensive for its construction. Nice appearance however, flexes under moderate weight not for heavy items.

Great addition!

Size: 40 Inch, Color: Rustic Brown, Number of Items: 1

Floating shelf was super easy to install and is a great addition above my window in my office. I used it to put some display pieces my wife wouldn’t allow me to put over our mantle. Very sturdy and looks great!
