Shelves look nice, but not great quality and one of my shelves came crooked (installed it perfectly level). Also has defects around the edges. Already installed so don’t want to rip off wall and return, but would like if they sent a couple new replacements at no charge. Keep you posted if that happens.

Sturdy, Stylish, and Easy to Install Floating Shelf

Color: White, Number Of Shelves: 1, Size: 35.4 inches, Color: White, Number Of Shelves: 1, Size: 35.4 inches

This floating shelf looks great and feels very sturdy once installed. It’s stable, fits securely on the wall, and holds plenty of items without issue. I measured beforehand, and it fits perfectly in the space I needed. The hardware was included, and assembly was quick and easy—I had it up in just a couple of minutes. The quality is excellent, and the clean design adds a nice touch to the room. Highly recommend!

It’s meh

Color: Natural Oak, Number Of Shelves: 1, Size: 35.4 inches

Instructions are different than what comes. It’s hard to level and because there isn’t as many mounting points as the instructions it’s more flimsy than you’d think. Still works but can take some finessing to get it to be sturdy enough depending on what you’re planning on putting on it. Looks good and like the pictures though.

Light weight but solid floating shelf

Color: Black, Number Of Shelves: 1, Size: 47.2 inches, Color: Black, Number Of Shelves: 1, Size: 47.2 inches

Having looked around at brick and mortar stores around me locally I had a really hard to find one that was long enough to fit my wall. Glad I was able to find the Balucci floating shelf 48'. As a collector or toys and memorabilia from my travels I wanted something in my room that could hold a substantial amount of small toys and items. Installing was very easy pretty much securing the base with the hardware provided. And securing the base to the shelf itself. I'm very happy with the quality and also the strength of the shelf. Even with a good tug it was very tight. Maybe some longer screws would be more secure but I think the ones provided were good enough.

Simple, easy, and strong

Size: 16 Inch, Color: White

Kind of on the smaller side but for the price it’s just fine. Easy to install with just a screw driver if you can miss a stud, else you’ll need a drill. Strong enough to hold what a normal person would put on a shelf that size. No worries and it looks great
