I don't often write reviews but these shelves are so perfect and well-made that it would be criminal not to share. 

My biggest issue with these types of shelves is that the brackets are often welded (creating a weak point that can shear) and the wood isn't solid. These brackets are a single solid piece of metal bent into the appropriate shape, which means there's no weak point and pretty much zero chance of them breaking. The wood is solid and straight, and even smells like it's been handmade. All of the hardware you could possibly need is included, including two different types of wall anchors. I love all of the sizing options too, these shelves are so versatile. 

It took my SO and I about two hours to get them mounted, with the majority of that time spent measuring and leveling. The actual install itself took about 15 minutes. 

Five stars. Will absolutely buy again if I need another set of shelves.
