$17.95 seems a little steep but.....worth every penny I’m sure.

But that is 1950's pricing. I can get you one for $99.99, and if you call within the next 10 minutes, I'll toss in a second one for free! Just pay for separate postage and handling.

Nah, I can get that functionality on my smartphone. Srsly, they have magnetic field detectors apps.
