For the second time are second to none in this product price and performance ratio. The Umkippunterbrecher calmed me right from the start. The heater is very noisy, but that did not bother me. He warms wonderful on stage 2 and quickly. The switching stage 3 I do not use so much since then, unfortunately, the dust begins to burn, the yes but logically runs through the fan inside. The stink and make a nervous. I would recommend this highly enough Heizlüfterlein =)
