This device has worked quite well for us, reliably allowing an elderly family member to call for assistance over the length of our fairly long house. We're finding that a set of three LR44 batteries for the necklace lasts a week or two and they are fairly expensive if purchased in the local drugstore. I've found a 15-pack here on revain to be a much better deal.
