I bought this to replace a soda can tray that I'd been using to organize cheeses on a shallow fridge shelf, and it's such an improvement. The other trays were fine, but kind of heavy and clunky to pull in and out. With the wheels on this bin and the lighter-weight design it's so easy to roll in and out and access everything at a glance. Such a good purchase. Also bought the 6" width and they fit great side by side on the shelf.
