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.

Simple, easy, and strong
Size: 16 Inch, Color: White
Kind of on the smaller side but for the price it’s just fine. Easy to install with just a screw driver if you can miss a stud, else you’ll need a drill. Strong enough to hold what a normal person would put on a shelf that size. No worries and it looks great
