bought the foot warmer for my husband. Yes, there is. Not only women have cold feet. He is very happy with it. Warms very good, is super easy to use, keeps the temperature (not cold once again when the power is off). However, the massage balls are a bit strange. I put a small towel under the foot bag, can remove the one and wash. Power heat-moderate nothing, but is more comfortable on the soles. I would highly recommend the foot warmer warmly. By the way. Lt Label on foot warmer it needs only 20 watts. It is powered via a 12 V adapter to the power.
