Nice shelves. Install was super easy except on one of the three shelves. The main mounting shelf holes were off so the shelf will not slip onto horizontal mounting poles unless I modify the shelf. So a 20 minute job becomes a two hour job. The mounting system does appear very sturdy just not aligned.

Love the shelves. Nice touch to my bathroom. Easy enough to install. They're not holding anything too heavy so can't speak too much on that but they do have a nice width.

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
