Sturdy and easy to install
Size: 12 Inch, Style: Black 6Pack
These shelf brackets come with screws and are easily installed. Very sturdy and can hold 14 hardcover books easily. Would recommend these shelf brackets for use to hold things to the wall.

Needs heavier duty wall anchors
Size: 10 Inch, Style: Black 6Pack
Brackets are nice and sturdy and look great in my son’s room. The included mounting hardware is not strong enough to support the brackets and shelves and I had to purchase heavier duty wall anchors, other than that great product.

Great Product for my coffee station shelves.
Size: 10 Inch, Style: Black 6Pack
I've used these brackets in two different homes, and they have performed exceptionally well. They are durable, sturdy, and have held up over time without any issues. In addition to their strength, they look great and add a nice finished appearance wherever they're installed. I would definitely recommend them and would purchase them again.
