Good for light stuff
Color: Black, Size: 15 inches, Color: Black, Size: 15 inches
Good product. Very light though and if it’s in dry wall won’t hold something really heavy. I don’t think it would hold 20 pounds just light. I put over my washer and dryer and put one right on top that way I can put heavy stuff on that side without it weighing down and being ripped out of the wall. I won’t be putting heavy stuff on the right side I used 4 pieces and the wall is about 60-62 inches long

Perfect sized floating shelves
Color: Black, Size: 24 inches, Color: Black, Size: 24 inches
These are great and the perfect width. I had my contractor install them because my tile had to have a hole drilled into it. I love that it looks seemless and flat to the tile. New bathroom renovation. I am very pleased. Holds a few towels also candles and a little plant with extra space. Perfect for a minimal look or if you have a small bathroom. Color was spot on.

Not What I Expected
Color: White, Size: 32 inches
This set of floating shelves was a disappointment. They’re advertised as holding 20 pounds, but mine began to bend with barely 10 pounds on them. All the screws and anchors were installed tightly and correctly, yet the metal brackets still warped under minimal weight. The shelves look fine on the wall, but I’m leaving them up only because I don’t want to patch a dozen holes—not because they’re sturdy. Definitely not the quality or strength I expected.
