Bests & Worsts Reviews from Amazon

These did not arrive in airtight packaging, which means they were able to absorb moisture during transport. Indeed, some of the packets appeared to be partially saturated when they arrived. If you're having them shipped to a humid location, you may end up with a less effective product. This is especially troubling since the manufacturer recommends that they NOT be reactivated in an oven. They're for single use and that's it.
