I use this foot warmer regularly because my office is in the basement and is covered with laminate. Accordingly fußkalt it is there and if you work 8 hours or more, you just need something that the cooling counteracts. This job meets the Bosotherm Fußwärmer without question very well. He turns corresponding to the instructions for use on its own, yet it can be reactivated via moving the switch immediately.
The only drawback is, in my view is the right rigid power cable that is connected up to the heel side of the foot warmer. I would have a more flexible cable on the front and a separate regulator found practical top of the heel side.
