I've got a two zone one. If you crank it up on high, it'll literally make the bed rock. It tells you not to put it on your chest 'cause it'll stop your heart.
I had 'em both on and needed another Coke, so off to the kitchen I go. Half way there, the top one, which was set somewhere around medium, fell off onto the floor. The Old Hen, knowing my back was killing me, said, "I'll get it". Before I could get out, "NO!", she bent over, picked it up, and slung that puppy across the room while screaming like a gut shot Comanche.
I had to laugh.....
