I think the design of this is very clever. I hope I never have to use it, or if I do, that I can remember where I put it. I had to smile when I read the directions and they say something like,..."if you get bit by a snake, don't panic and run as there is a good possibility there are other snakes around,"....what a great thought! :) Anyway, I think how this product is made and how it is to be used makes it very functional.
