Bests & Worsts Reviews from Amazon

never thought i'd need to use it, but sure enough, i got stuck in a tree well while skiing. scary as hell. i have it attached to my zipper pull on my patagonia shell jacket. which made it easily accessible. that's a big deal when you're hanging upside down in a tree well, using one hand to hold onto a branch for dear life. i blew this thing like my life depended on it. sure enough, after about 5 minutes, another skier heard it echoing through the woods and found me. fortunately i wasn't immersed in powder. i could breathe and extract myself after i calmed down. could have been much, much worse.
