Love the service so far. Was afraid ATT would not work where I live, but it works fine. Service picks up immediately. Had a couple of issues that we are working out. The fall detection is very sensitive. You must hold button down on pendant to cancel fall detection alert. It goes off when you sit in a chair and don't move for a couple of seconds. It goes off when you are sleeping for no apparent reason. My husband (user) went out on back porch in middle of night and fell asleep in chair. He did not take his portable speaker with him which was charging in living room. Main speaker was in living room too as well as my cell phone. A fall was detected. I was in the bedroom and didn't hear alert. Next thing the ambulance and fire department were at our door. We have remedied that problem by putting charger for portable unit in the bedroom so at least I should wake up and hear it. My husband has severe arthritis and has problems with mobility. He has fallen in the past. This unit gives me peace of mind.
