Assembled in under 3 minutes. Broke down in 1 min. The part doesn't fit. So if you pull on it, it just falls apart. If you have tiles the very small wheels will get stuck in the grout and you will end up having to demolish the top shelf to get it rolling. Very very narrow. That's a plus for some. I would like something wider. It is as wide as a ketchup bottle or ketchup bottle.
