These are great storage cubes: perfect size for my needs, they look good, but are also lightweight and made from recycled, sustainable materials that are surprisingly sturdy.First one I built was a bit tricky and the sides fell down on me a couple times before I got the hang of it. Second one I had done in five minutes. No sweat. Putting the cubes together was actually kinda fun.Here are a few tips:1. Use some wood glue for an easier build and sturdier final product. Just dab a little in the dowel holes before you put the dowels in. The adhesive tape is adequate, but it goes smoother with a tiny bit of glue. You don't need a lot.2. Don't get frustrated when the first couple pieces don't stay upright on you. It takes a tiny amount of practice. After you put together your first cube, you could probably start cranking out like ten an hour. I think some of the reviewers here gave up too quickly and did not use glue like I did.3. It is not meant to be picked up from the underside of the top piece, especially when there are books or other items inside. That will pull the top off. No adhesive is that strong. Screws in particle board aren't that strong either. Pick it up from the bottom or take everything out of it before you move it. Use common sense.That's pretty much it. I shopped around a lot for similar products but I kept coming back to this one. Finally I gave it a chance and I am glad I did. If you consider yourself capable of assembling a box, you can do this. It is cheap and lightweight, yes, but for all the right reasons.Best of all: Sustainability!
