Thankfully I haven’t had to to use it yet, but it looks good.
I having had to us it yet I am sure it work I hope.
I live alone, and I don't want to be a statistic. One device is at the table for my main meals, the other is in the TV room where I have snacks.
Have not had to use it and I hope I never will. I just feel much better just having it here available.
