This Fußwärmer I about 2 weeks getestet.Der first major drawback is you must first have an adapter to put the device into operation to können.Wenn in the German market such devices are sold, one would assume that one without this foot warmer additional accessories into operation kann.Mit the function I am very zufrieden.In short time is the Fußw. pleasant warm.wann lights which control lamps and how they view, it is not clear to this day. Therefore only 3 stars
