...got wack-a-doozie heat?

We've used them for years too. Before moving here full time, we'd leave the house thermostat set to 50 degrees during the week, so the mattress was cold when we'd arrive. Part of our "open up" procedure was to turn the mattress pads to "full blast", and all was fine by the time we'd go to bed. Now, we use them on low, while leaving the bedroom thermostat to 62. Works out great. The only concern is the electromagnetic waves we are absorbing from the pad.
