Query: No goldilocks spot

I've had this for over a year and it just annoys me. I like the design, it is easy to wrap around a knee etc, but that's not enough. Even the lowest setting is too hot. I spend all the time I use it turning it on and off because there is no goldilocks setting that is just right. All the settings are too hot. I think they should start putting a dial on heating pads instead of settings that the user cannot control.
