Pure Enrichment Deluxe Foot Warmer

I have poor circulation in my legs, and I hoped this foot warmer would help. It failed miserably. The product description on Amazon and the instruction booklet list the temperatures for the four settings. The high setting was supposed to produce 140 degrees F. After warming 20 minutes, an infrared thermometer showed only 82 degrees. There is no heat on the top, sides or back. Thus, my toes stay cold. The instructions say, "If the unit does not turn on when you press the power button, make sure the Control Connector is securely plugged into the Pad Connector." I can find no connector. The cord from the controller runs directly into the heating pad. This thing is pitiful. I would give it zero stars if I could.
