They look good and seem well built.
Color: Brown
These are very well made and look really good. They ended up being too small for my need, but that was my fault on measurements. I would highly recommend if you are looking for corner shelves.

slightly annoying to hang
Color: Brown
A little annoying to hang but look great and seem to be holding up well! I have heavy plants on them and no issues at all!

Functional, Look Great
Color: Brown
These were nice corner shelves that were easy to install, and look great. There are plenty of other options on Amazon that offer more shelves and/or at a lower price, but these ones look nicer than most.
Overall they're pretty easy to install. It's not exactly a two-person job, but it is easier if you have help - someone to hold the shelf and a level, and the other to mark the holes. My only other recommendation is to check your L-brackets before you do anything. Some come bent inward, some bent outward. If they're really crooked it will make it hard to wedge the shelf into the corner and may result in uneven measurements/holes, so make sure you straighten them out first.
