I have the original and the newer mesh versions.
This device is tiny and awesome. Use while camping, hiking, sking, exploring, sporting events, long plane flights and even during the zombie apocalypse. I have multiple devices for the mesh factor. Recently I was leading 20+ non-outdoor people on a hike through trails. We split up in groups. We were able to effectivly communicate from one side of a mountain to another. (I placed one devise on the mountain peak the morning of). So for 12 hours I was able to track the location of each group coordinate medical attention (blisters and dehydration) accordingly. Get everyone back to the cars on time and back for dinnwr and whiskey. This is something that the radios failed to do. (Trust me we tried). I keep a pair in my glove box just in case we end up at a large even where cell coverage is lacking or could be an issue. It is a piece of mind knowing I have it if I need it. If you check out the webpage and see how many others have them it's really cool. There So many uses I cannot name them all. Lets just say its such a great idea our troops are using them.
