How does the Produce Saver work? It's meant to extend the life of your produce by providing air circulation beneath produce (a raised tray allows for drainage), while also filtering oxygen and carbon dioxide in and out of the container's lid, avoiding ethylene gas buildup, which leads to ripening and decay.

The green bags do work for certain types of produce. Some caveats–the shelf life is extended as long as the product is very dry (mold growth appears to be a problem in damp produce). Also, the bags have a shelf life and can only be reused 10 times.

I found them in the back of the refrigerator almost TWO WEEKS later, and they were still good. The real miracle is how long it keeps zucchini. Zucchini starts to get mushy in the crisper drawer after just a few days. Again, these miracle containers have kept it fresh for close to two weeks now.
