I have Life Alert - it's awesome. I have a bad history of heart attacks in my family but I don't exactly want everyone to know by wearing the necklace or arm bracelet that comes with the system. I prefer to wear it discreetly so I created a case that would hold the Life Alert Module. I was going design a band as well out of Ninja flex (I still might) but I looked everywhere and discovered that a small, padded(my ankle is 10" circumference) dog collar. It fits really well and i can't even tell it's on. It can be worn in the shower or just about anywhere and can be very quickly removed with buckle. so I decided not to reinvent the obvious. I hope this helps someone.
