The wood shelf part is very nice, but the hardware is lacking for this length of shelf. The bracket that mounts to the wall is very thin metal, and mine was warped so that I had to bend it a bit to mount it straight. It also allows the shelf to bounce at the slightest touch, even though it is attached at the studs. I had to use a couple of chair brackets on the bottom of the shelf to keep it steady, which kind of defeats the "floating shelf" look. That said, with the brackets it is now quite sturdy and doesn't look bad at all.

STUNNING!

Absolute perfection! Beautiful NATURAL, solid wood. These are not your straight manufactured shelves. These shelves are beautiful with all of their beautiful characteristics. No two shelves are a like and nor should they! I highly recommend the live edge boards for an upscale look.

Needs better hardware

Shelf looks nice, but it’s a heavy piece of wood. The hardware that’s included is not strong enough. The hardware broke and the shelf fell the first day.
