Great value for a quality food storage. Lids fit snug against glass, easy to clean, and glass pieces stack nicely on top of one another. I can't stress enough how important it was for me to have an easy-clean but snugly fitting lid, as some of the other food storage systems have multi-piece lids (which are definitely snug) and hard/time consuming to clean. Easy to clean makes it easy to keep clean!

Pros: Easy to clean, stacks nicely, various sizes for various storage needs.
Cons: Would love different colored lids!
