We signed our Mother up for the Mobile Help service because she has had a few falls over the last year and are grateful we did! She has had one false alarm and two falls since she has been wearing the device & it's a relief knowing that this device works as it should! The device, when triggered immediately sends out a text and an email as well as a phone call from a Mobile Help Center operator who dispatched emergency personnel to her location. We haven't tried other devices before signing her up for Mobile Help but we did research all the devices out there and felt this one was the best one on the market for her needs!! I would definitely recommend Mobile Help!!
