Oy. It's this kind of product which really makes me wonder. Called the Showing Beacon, this ridiculous piece of equipment is a wireless device used to alert anyone who might be selling a house that anyone looking at it has left the premises. It plugs into any phone jack and with a push of the big red button, alerts you on your cellphone that all's clear to come back. Why, dear god, any Realtor couldn't just call the home owner when the clients have left the house is beyond me, but this piece of shit will run you $80 for the hardware and another ongoing fee of either $40 for a listing plan or $99 for an annual plan. Fascinating, really.
