I dislike the entire concept of having to wear this thing because it reminds me that I'm not a kid anymore, but that's hardly the device or the service's issue. I do feel more secure with it than I do without it, and my growing number of healthcare providers all congratulate me on having gotten it. And the process of signing up was quite simple and initializing the device was too. I took off one star because I feel the accelerometer that detects falls is just a little too sensitive. I suppose too sensitive is better than not sensitive enough, but it's annoying to hear "Fall detected!" because, among other things, I'm working at my lathe in my woodshop and the vibrations from the machine set off the alarm.
