To be honest, I didn't expect it to work as well as it does. I tested it with avocados, and they are just as green the next day as when I put them in, and only a slightly noticeable difference two days later, and that alone is amazing. Haven't had a chance to use it much yet, but am loving it so far. I especially like how the design keeps the small lid adaptor attached since I rarely use small lids, but because it attaches, I'm not worried about putting it in a "safe place" and losing it!
