I have had these for about a week and so far i am not happy with them. They look good up but they are made only of thin particle board, the brackets do not not hold tight, i used the included Sheetrock holders and screws and i think the screws are to big for the holders and just dont hold well. Currently my shelves are empty because when i put something on them the shelves tilts forward. I am trying to decide if i can fix somehow or if I should just return them.

Great product

We have ordered this item many times. Easy to install and looks great. My son uses them to store/display his car model collections. We also used one to hold a sound bar in the living room.

There junk.

Color: Walnut, Size: 55"W x 12"D, 2Packs

These shelves are junk ! I had to wait 3 months to get them because they shipped by mule train which is ridiculous. The metal brackets that attach to the wall are weak. The shelves sag. They are not level front to back. Do not waist your money on these.
