Yes, just like in the infomercials.
It's a gimme from one of the conferences I went to a few months back -- actually, it was part of the speaker's gift bag. I wasn't a speaker, but I met someone who was, and he was kind enough to share (so, thanks Dave).
I just got it today; I cleared out a spot for it on my kitchen counter, but I'm kind of skeered to use it.
In addition to stretching out your food budget, it's also good for waterproofing and protecting other things, like survival or first aid kit components, etc.
So this kitchen gadget might actually save your life someday.
