Did you notice?

My Mom's (can't remember the name of the gadget) wouldn't work as advertised.
We finally ended up with a phone that she carried in a case around her neck. So she could call 911 herself or talk with friends.
Everybody's different and some things are a hard decisions. We found the phone option best for our situation. Yes, (painfully slow) learning curve if she hasn't been exposed to a med app or receiving medical report as text message.
But hay, thanks for thinking about MOM. You only get one.
