Great value and easy to install!
Color: Black, Color: Black
I only needed 3 of the 4 shelves so I have one as a backup! Very easy to install as well. The shelves feel sturdy and I’ve never had any issues!

quality matches cost + instructions unnecessarily tedious
Color: Brown, Color: Brown
The material is real wood but don't assume that means quality - it's still very cheap feeling, and very lightweight. But once installed they are quite stable, and they look great from afar. I got a darker colored one and the stain does come off very easily. One of the shelves had a huge manufacturer sticker on it and it took off the stain when I removed it, and a bit of the stain also came off when I wiped the shelves down with a wet cloth. It'll be dry dusting from now on, I suppose.
Also, they did not fit snugly into the corner - when one side is pushed flush to the wall, it forces the other side to pull away from the wall a little bit. It wasn't a drastic space, maybe like 1/8th of an inch, but it is still something to note. I am fine with the cheap quality as they are, after all, pretty cheap, so I'd say they are worth exactly as much as they cost. Personally I am happy with the purchase - just thought I'd warn.
Secondly - if you want to follow the instructions exactly, you will need two people unless you have inhuman agility. But I also think the instructions were a bit asinine and tedious. They want you to line up the LOOSE shelf and brackets with a leveler to mark where the brackets go on the wall, then put in the wall screws, hang the brackets on them, balance the shelf on the brackets to mark on the SHELF where the brackets will be attached, take the brackets off the wall to screw them into the shelf, then put the combined shelf-bracket unit once again on the wall screws and finally screw those in tight.
In hindsight, you can just mark where the brackets should go on the SHELF (not wall), screw the brackets into the shelves, THEN level the shelf on the wall and screw the whole unit into the wall together. We were really baffled why the instructions didn't have us do that instead of spending extra time (and frustration) trying to juggle all the loose pieces and tools. But I'm not engineer-minded, nor have I ever installed corner shelves before, so maybe there would be some kind of issue with doing it that way that I can't predict.

Good shelving decor
Color: Black
Easy to install and perfect for a corner display of Disney decor. They are lightweight, so we didn't put anything heavy on them, but the brackets seem sturdy enough that we could probably put something moderately weighty on them.

GREAT BUY
Color: Natural Wood
LOVE these shelves! Got them for each side of the bed to put books. Really elevates the room, and is cuter than just a simple straight book shelf.
