We've always had issues with our chips, cookies, snack nuts, etc., staying crisp after opening (even though we were careful to reclose the bags with chip clips or whatever other method was available). With the Brisker we can now keep these items fresh without even closing the bags they are in. In addition, these snacks are actually warm when we take them out of the Brisker to eat, which is a real plus. Wish we had tried the Brisker sooner.
