Not bad but could be a little more sturdy. We used longer and a little larger screws to try to make it better and that did help but it still has a little wobble in it. It will serve the purpose for me in my bathroom. They look nice except it would be nice if they would include some of those little covers to go over the screws in the bottom of the shelf so you wouldn’t see them. They really show up on the white shelves.
