I love these shelves (I purchased 6 shelves total). The size I got was perfect, looks phenomenal, & quality is great too! Only negative thing I’d say is that it could be difficult for some people to set up as it needs to be leveled, & can be hard to align with other things since the part that attaches to the wall is separate from the shelf (due to its floating design) but once it’s up, it looks great. Definitely good value for money with its quality. I have them to hold up decorations/toys, & you think some of my shelves have about 5lbs of stuff on it & I’ve had no issues, so functionality is good.
