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.

Very sturdy.
Size: 12 Inch, Style: Black 8Pack
Great buy compared to similar product at Home Depot. Screws can be made of a better quality metal. Overall very sturdy. Fits 2x12 lumber great.

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.
