Product review (4 stars): Great produce protector.
Have used similar products in the past and have been unable to locate them when it was time for them to be replaced. Found an ad for these in something else I had purchased. Ordered a 9 month supply (2 packs) and have been especially happy with the produce results. Salad is hard to tell, because sometimes it is already browning in the bag. Overall happy with the product. Especially like the gauge on disk that shows how much time is left before replacing. Would hope they are still available in 9 months when I need to reorder.
