Example Input: This is the worst purchase on Amazon I've ever made. The cubes fall apart anytime you try to move the cabinet around the room. The cheap plastic fasteners they provide to secure the cubes are a joke. You'd probably be better off using duct tape. The material is very flimsy particle board that is basically cardboard. I moved recently and the entire thing fell apart. When I re-built it, the particle board disintegrated and the whole thing ended up collapsing. On top of that, it's too shallow and small to really store anything.
Example Output: 1
