Saved my life, it did, a good number of times. Good thing, too. Nobody else could have shut it off. Would have been a devil of a time getting it off the idiot who tried to get in. Well, for a while, at least; after the idiot was dead it would be easy, but then it would be after the doctor probably. Stubborn as a mule.
They were pricey, but now things have progressed, and now they’re more reasonable.
