My 70 year old mother-in-law that lives with us. She fell hard and broke her wrist and fractured her spine 2 weeks ago. She is at home. We needed a way for her let us know she needed us since she wasn't able to use her mobile phone with her injuries. This device was perfect. Put it around her neck. She presses the button on the receiver sound goes off. My wife even takes the receiver and plug into an outlet in her home office in our detached garage. Still works from that distance. Works great.
