My dad has one. It works outside of the home as well. He started with the bracelet but it kept hitting things PLUS you need to carry a separate item in order for the bracelet to connect to their system. He called and they returned free of charge and sent him a necklace instead that has the whole system in the necklace part. It costs a little more.
Not sure which brand he went with.
