Great addition!
Size: 40 Inch, Color: Rustic Brown, Number of Items: 1
Floating shelf was super easy to install and is a great addition above my window in my office. I used it to put some display pieces my wife wouldn’t allow me to put over our mantle. Very sturdy and looks great!

Looks Good-Not at all sturdy
Size: 40 Inch, Color: Rustic Brown, Number of Items: 1
Looks good. Not sturdy at all if you want to put any weight on it. It’s purely decorative and is not a functional shelf. I had to use toggle bolts for a hollow wall install. The hardware included was not helpful.

Poor quality product, hardware not appropriate
Size: 24 Inch, Color: Black, Number of Items: 1, Size: 24 Inch, Color: Black, Number of Items: 1
Do not waste your money on these, not as described, very cheap, hardware does not work. Going to have to repair my wall before I can do anything else. Completely unacceptable product. Very frustrating and was not properly represented in the marketing advertising. Do not buy. Would like to return, but waited 3 days to long. If I had opened them immediately I would have seen the poor quality.
