Great shelves
Size: 16.5 Inch, Color: Rustic Brown
I loved these for my room, they were easy to install and super versatile, I love how easy it was to assemble them and how functional they became once I was done setting them up. They fit perfectly next to each other and I love how my room looks nice since I don't like relying on bookshelves or anything of that category and rather have wall shelves. They are really stable and I love how they look, they are also really easy to clean since I spilled some baby powder from my last waxing session and they clean up pretty well. Overall, just know that these shelves are super stable, durable and versatile, I love how many things can fit on it if you know how to organize or don't have much stuff to put on them; it's all up to you and what you need them for, so I recommend them 10/10!

Great shelves! Had for years!
Size: 16.5 Inch, Color: Rustic Brown, Size: 16.5 Inch, Color: Rustic Brown
I love these shelves, I’ve had them set up both ways, as a floating shelf and the other way where you get some side support. I’ve had them for years, moved with them, and they continue to work great. I’ve had a lot on them too weight wise (I love books) and they don’t cave in the middle. Great shelves and easy to assemble (I’m a newbie with a drill). Great value for the money, durability is great, adjustable, and great for what you get!

Budget-Friendly with a Rustic Charm - WOPITUES Wood Floating Shelves Set of 6
Size: 16.5 Inch, Color: Rustic Brown
The WOPITUES Wood Floating Shelves Set of 6 is an appealing option for those looking to add a touch of rustic charm to their home without spending a fortune. This set of six shelves offers great versatility and functionality, ideal for displaying a variety of items such as books, plants, and decorative pieces, enhancing any wall decor with a farmhouse vibe. Upon installation, which is straightforward with the included mounting hardware, these shelves provide a neat and organized look. The ability to arrange them in various configurations allows for creative freedom in decorating, making it easy to personalize your space. The overall capacity and sturdiness of the shelves are commendable, holding up well under the weight of typical decor items. However, while the shelves perform well from a distance, a closer inspection reveals that the materials look somewhat cheap. The wood finish, although attractive from afar, does not hold up to close scrutiny, with the texture and detailing lacking the quality one might expect from more expensive shelving. This aspect might be a downside for those who prefer more authentic, high-quality woodwork. In conclusion, the WOPITUES Wood Floating Shelves are a solid choice for anyone on a budget looking to enhance their home decor. They offer good functionality and aesthetic appeal at a distance, though they may not satisfy those looking for premium material quality. For the price, they are a worthy consideration for casual use and decorative purposes.

Good product. Real wood. Sturdy wall anchor.
Size: 16.5 Inch, Color: Black
4.5 stars. It's a great product. The pictures made me wonder if this was wood or plastic, but it is definitely wood. It is very attractive and fairly easy to assemble. I feel like the harnesses for the wall don't fit the wood well enough, so you can get different distances from the wall, and one of my shelves is half a centimeter below the others, even though I lined it up the same. But they are sturdy shelves and very pretty. My only real complaint is the screw anchors for the walls. They are SERIOUS. I doubt these will ever fall out of the wall, for real. The only problem is, they eat the wall as you are putting them in. If I ever decide to move these, I will have to do some serious dry wall repair.
