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.

Great center piece for my gaming room
Size: 7.9"D x 39.4"W x 34.3"H, Color: White, Size: 7.9"D x 39.4"W x 34.3"H, Color: White
It’s quite large, but you can display a lot of your cool collectibles on it. It arrives in a nicely packaged box with instructions, although I found the instructions to be quite basic. Most people should be able to figure it out.
Instead of following the instructions, I recommend forming the honeycomb structure on one side and then attaching it to your wall. Drill holes through the holes in the honeycomb, ensuring everything is level. Once the entire unit is assembled, one person can hang it on the wall. However, I suggest having a building partner. I attempted it alone and was straining my core while reaching on a ladder, which was probably not the wisest idea. The build quality appears to be very good, and I believe it will last for many years. The LED light colors are nice, though not as good as those on a razor, but they’re not bad for a third-party product. There are plenty of screws to install, with a couple of extra.
Just for reference my computer screen in the g9 57 inch that’s how big this shelf unit is. Holds up to 120 lbs
