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.

Great quality

Color: Rustic Brwon, Size: 16in

Hassle but they work great. I love the color, the thickness and quality. They do have some weight but in my opinion, I prefer that. Right now the four shelves are holding up my WiFi routers and remotes. Will buy again
