.0 out of 5 stars Bought as a compromise, but they are actually better than FoodSaver containers. Great value.
I purchased these as a lower-cost alternative to the ones from FoodSaver. The plan was to see if I could adapt them to the FoodSaver system. After using them, I realized their manual system actually works better and are easier than the FoodSaver system.
Open container. Put stuff in. Close container. Place pump over the green seal. Pump a few times. Done.
No waiting for a machine to start. No moving to that machine. No waiting for the machine to remove the air. Also, these containers create at least as good a vacuum as FoodSaver, and likely better. To open, simply thumb the green tab to release the pressure then open like any other container.
By the way, I'm a huge FoodSaver fan, however, for containers, you can't beat these for the price.
Compression: Since the lid and sides are relatively flat (compared to FS domed construction), they do bend in under extreme vacuum. This is not a problem and it does not compromise the integrity of the package.
All things considered, I would not trade these for FS containers, especially given their much easier sealing process.
