I have the wrist Samsung Gear S3 Frontier.. Previous Great Call and Life Alert.. Desired only one unit on my person working outside. This Samsung wrist unit appreciated. However, it has difficulties. GPS does not work inside large business building. The wrist Samsung has a battery life of about six hours. Sometimes difficult to get it adjusted on recharging stand....frustrating. Nevertheless, only wanted it while working outside on my property....very happy with this aspect of Samsung Gear S3.d The technical staff has been extremely helpful, kind, patient and working with me diligently. The wrist unit is new for MobileHelp so I am willing to be the "guinea pig" as the problems are resolved. I have no intention of returning the wrist unit .....it is just what I was looking for in an emergency alert......76 years old male. Can not add photo as no cell phone and limited knowledge of internet. Thomas Edwin Koepke DVM retired. 651-457-1350 Customer #1653202 10/30/2018
