    Easy to Hang
    Color: Black, Size: 3 Pack
    This shelf is easy to hang, comes with great anchors and looks perfect. The quality looks nice and is was an easy hanging process compared to other shelves. Worth it for the price.

    One of the best deals available!
    Color: White, Size: 2 Pack
    Extremely sturdy, good looking and easy to install. I have a couple of dozen feet of assorted lengths in the kitchen, bedroom, living room and foyer. Holding all sorts of antique clocks, audio equipment and cooking stuff from my flours and assorted cornmeals to cases of powdered “lemonade”.

    Mounting system doesn’t align on one of three shelves.
    Color: Walnut, Size: 3 Pack
    Nice shelves. Install was super easy except on one of the three shelves. The main mounting shelf holes were off so the shelf will not slip onto horizontal mounting poles unless I modify the shelf. So a 20 minute job becomes a two hour job. The mounting system does appear very sturdy just not aligned.

    bought these after another set of floating shelves didn't work. these are great and an awesome value!! i've used these in my guest bathroom and also throughout my house. they look great everywhere and are much easier to hang compared to others. my husband was hesitant after the last shelves but these turned out amazing. they are very sturdy and hold a good amount of weight. i would recommend buying these compared to any others.
