Good Shelves
Color: B. Rustic Brown - Americana Farmhouse Style, Number Of Shelves: 3, Size: 22.5inches
These shelves are really nice quality and look as advertised. The hardware included was great quality, metal drywall anchors and good screws. They were easy to install, and make even/level with each other. My only gripe is the price, but I'm very satisfied with the product overall.

Attractive, easy to install, nicely equipped hardware package.
Color: B. Rustic Brown - Americana Farmhouse Style, Number Of Shelves: 2, Size: 22.5inches
These are pretty doggone nice shelves and I appreciate the fact that they are not made of solid particle board. Yes they are made of an engineered product, but they are lightweight and strong…and look better than particle board products and more costly than their actual price. Easy installation system with the bracket…not fussy like some are. An especially thoughtful touch is the variety of hardware that is included. Also a tiny level for use when installing them. What? …So they can be installed correctly? I was pleasantly surprised by this inclusion.

If the set screws were white the shelves would be perfect.
Color: C. White - Modern Minimalist Style, Number Of Shelves: 3, Size: 15.7inches
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.
