One of my favorite Sterilite products, we use this cart in the kitchen (storing the children's dishes), the bathroom and the garage. The clear plastic of the shelves makes it easy to determine what is in them, while both the castors and the lightness of the units makes them very portable. Despite this, these units have proven to be surprisingly durable, with two of them being more than 4 years old. We haven't had to replace one yet, and we may be getting another one for the garage soon.
