Well, I dunno if you're still watching this space, but... I have two Flics deployed for my semi-disabled wife. One is configured to page me from the bathroom, it's stuck on the wall next to the bathtub. The other is configured to page me from wherever she is, and it is clipped to her purse strap. Although she's not totally debilitated, I do worry about her slipping in the bathtub/shower. The one that's clipped to her purse, is mainly for her peace of mind. In either case, it's easy to see why it's important that these things work with something approaching 100% reliability. So far, that's not been the case. So keep improving!
