Sounds like a good product and whatever level of prepper one might be this would be a good addition to have. I agree that $69 might be a little pricey, but it would be money well spent if I were ever in a position where I needed to use it. I like the idea of using something like this for gifts and for a way to get people to start thinking about self preservation in general. I may get a couple to add to the GHB's for the vehicles, perhaps of LB wants to chip in on one we could do a field test for everyone.
