I bought two of these because I have two of the Trolly Compacts. The cluttered look of the contents being visible has disappeared. The beige one is especially stylish. Even if you roll it around with things on it, the items on top hardly move at all, thanks to the non-slip finish. The first wagon is for storing drawing materials, origami, etc., and is for one person is located near the sofa, so I can now put drinks on it or open my laptop. The second one is a baby meal wagon for baby food, milk, aprons, etc. (previously, it was a baby wagon for diapers and clothes). I'm happy that I can put the finished baby food down for a while. The grooves fit snugly, but the one I bought later has a little more play in it, so it rattles when shaken. However, there is little lateral force applied, so it's not a problem. The price was reasonable, so it was a good purchase.
