Just before I purchased these 3 I bought 2 sets of 2 larger ones. The color is exactly what I was needing. They are packaged together so no scratches or damage. My husband (the installer) says they are easy enough to install. They are perfect for a diy update, durable and hold plenty of weight for their size. Happy happy customer

Good quality for the price

Seamless floating shelves that look and feel great. I opted to use different drywall anchors since I didn't trust the ones that came with the product. I have bad drywall and no studs where I was mounting so that doesn't fall back onto the product. The shelves are true to size and have held up great. The shelves themselves aren't too heavy so it leaves some room to add weight onto them. I used the 30in long shelf on the left and 24in long shelf on the right to create a nice corner shelf. There are additional screws on the bottom the keep the shelves from moving off the bracket.
