I purchased this set to augment an earlier set of the same containers that I have.  I've found these to be great, long lasting food containers.  This set has a nice variety of sizes but would be even better if it included 1-2 of the larger sized containers found in other sets.  

Pros: Great containers. Tight seal. Easy to open. Dishwasher safe.
Cons: Set could use one or two larger containers.
