Well my device went off a little while ago. I must say it is one heck of a jolt. It's like a pretty darn good electric shock that thank goodness doesn't last too long. Hurts like crazy, scares the crap out of me because it is totally unexpected, and then leaves me on edge for some time waiting for another one. They say if it goes off once to use my home reader to send them a tape by phone and if there is a problem that requires it they will tell me to come in. If it goes off more than once just go to the emergency room. So far just the once today.
Some of you guys know this thing has saved my life two other times. I guess this makes three times. I admit to being very grateful to the good Lord for having this thing, but I HATE how it feels when it goes off.
