I got one for free from Medicare/Medicaid-you have to have a "landline"..Due to "Lite up Texas"program,my phone bill is 10.00$ a month. I wear the pendant always,it's waterproof,so don't worry about the shower. It's very light,don't notice I have it on. They call every month to check that it's working,I press the button and reassure the box that all is well. It makes me feel more secure. The one that's advertised on tv is 50.00$ per month. Also a good company.
Hope your Mom is OK,scary all the way around.
