“Brown” floating shelves
Color: Brown, Number Of Shelves: 2, Size: 60"W x 6.5"D, Color: Brown, Number Of Shelves: 2, Size: 60"W x 6.5"D
These shelves are great, easy to install. My only complaint is the color is not quite what I expected. I ordered “brown” and they look a little more “walnut”.

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.
