Holes in brackets are not spaced for studs!
Color: White, Number Of Shelves: 2, Size: 67"W x 6.5"D
So the quality of this not great, but good enough and they look nice enough on the wall. However, the bracket holes are not spaced at 16" intervals. WTF? I'm not sure who designed this thing. The molly plugs that came with it look OK, but to play it safe I used a cobalt steel drill bit and made my own holes in the bracket. Easy enough with some wd40. My other pick with this is that the screws to anchor the shelf to the bracket are black and and very obvious... they should have supplied some kind of cap.

Nice, make sure the measurements are what you want!
Color: Black, Color: Black
I like these shelves, just make sure to read the measurements , because they are a little narrow, but perfect for what I used them for. They added a sleek look to my wall. I'm a very plain Jane kind of person and I've gotten compliments from my friends. I used them to put my crystal collection on and they are holding up. I did use these new screws and anchors from tiktok to hold them up, not the screws these came with because I don't like the plastic anchors. The size is perfect and with a little help with straightness, I got four up out of six.

Glue separated within five minutes of being hung up
Color: White
I do not recommend. As I was hanging them, the shelves looked like they were already going to separate. I hung them up and I put a couple books on a few different ones as well as some trinkets not weighing even 5 pounds (so not even close to the weight). Within five minutes. One of the shelves snapped. They look okay, are light and are super easy to use, but the quality is horrible. I would say the best part about this is the hardware and mini levels it comes with. Definitely not worth it. I’m sure you can find something better for the price.
