My mom has been using LifeFone and services for over 3 years now. She wears it as a necklace and it is light and comfortable enough for her to wear anywhere (but the shower). She has accidently dropped her Lifefone a few times and set off the device. Each time, a representative has connected with her through the device to ensure she is OK and it was an accidental alert. My family and I are very pleased and relieved that her LifeFone works so well. Thank you!
