Review on 👣 Cordless Heated Foot Warmer - Happy Heat Electric Feet Warmer for Office, Home - Portable Under Desk Heating Footwarmer with Auto Shut-Off, Anti-Slip Sole - Grey by Cody Unruh

This foot warmer is very hot and I have to take my feet out regularly to cool off, although my hands take the heat well. Of course this is not for those who are damaged in any way as it can burn; I would not put it next to a child or toddler. However, I like it because my apartment has very cold floors and my feet are always cold. Perfectly and quickly warms cold feet. This is a sealed water bottle in a foam pillow. The water bottle charging port sticks out and you can feel it under your feet, but I can put up with a little discomfort for the warmth. One thing I noticed is that if the bottle is not level when heated, the water will heat up in shallow water and the device will turn off. Then, when the colder water in the fuller area mixes with the hot water, it cools down quickly. If the bottle is lying flat when heated, the heat will spread evenly and the bottle will be so hot that it will barely fit in the pillow. It's like handling a hot potato. 1 year later: It still works fine. The hot-water bottle is put in, the light goes on, when the light goes out, the bag is usually swollen and very hot. Putting it in the fluffy thermal doormat right away will give you a very warm doormat, but if you forget the water bottle is plugged in, it will turn off automatically when the light goes out and cool down, so put it in the Foot pad later leads to a not very warm foot pad. The foot warmer keeps you warm for about 2 hours. I'm still very happy with it because it keeps your tops, bottoms and every part warm. I still occasionally remove my feet as they get uncomfortably warm. So you don't want to fall asleep while using it. I use it while working on my computer with a cold wooden floor so I don't sleep or watch TV before bed.
