    Nice shelves. Minor defect in one of mine.

    Sturdy and easy to hang. Look nice. One of the set screw holes was off by 1-1/2” so I had to drill a new one, that wasn’t ideal.

    Nice looking but bad quality and defects
    Color: White, Number Of Shelves: 2, Size: 60 inches, Color: White, Number Of Shelves: 2, Size: 60 inches
    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.
