This product exceeded my expectations. The installation process was incredibly straightforward—even for someone with little to no experience—and the instructions were clear and easy to follow. Once installed, it feels very sturdy and secure, with no wobbling or shifting at all. You can tell it’s well-designed and made with quality materials. I also appreciated how quickly I was able to set everything up without needing any extra tools or help. Overall, it’s a reliable, user-friendly product that I would absolutely recommend to anyone looking for something dependable and easy to install. Drill is required though.

Don't buy

Size: 23.6 Inch, Color: White

The shelf is very flimsy and not sturdy at all. It feels unstable and poorly made. Definitely not worth the money, I wouldn’t recommend wasting your time or money on this product.

Clean look and very sturdy

Color: Brown, Number Of Shelves: 2, Size: 36"W x 6.5"D

These floating shelves look great and were easy to install. The invisible brackets give them a clean, modern look, and they feel sturdy once mounted. Perfect for adding storage or décor in a bathroom, living room, or bedroom. Great quality for the price.
