I've used her green bags for years, but only for certain things like tomatoes, peppers, cabbage, some types of lettuce, and a few others things. I thought they would work with bananas, but my bananas keep better just on the counter or in the little plastic bag I bring them home in... never keep them in green bags.
Tried the green boxes once, and it was a total disaster. Put paper towels in for the moisture, etc. -- no luck. Some things just totally rotted, and no way did anything I tried keep for even 10 days, let alone three weeks like she says. Sent them all back. I just cannot force myself to believe anything she says about those boxes on the air.
