I have it for the same reason. I have a falls alarm, but the pendant has a metal chain that I'm allergic to. It lives on the bedside table and only gets used to test the system.
The watch can be voice activated—so it doesn't matter if your arms got pinned under you when you fell, or your glasses slipped off and you can't see what you're doing—and it has a silicone strap that can be worn 24/7.
The watch doesn't record all this stuff on its own memory, by the way, it uses the iPhone it's linked to.
It was easy to turn it off once I had the instructions, but there was a step about backup to iCloud that I could have missed if tried to fathom it myself—I was new to the system then and didn't quite get it. I can look easily it up again, so DM me if you have trouble.
