Have I bought years ago this device that makes quite satisfactory warm. However, the processing is rather poor, which is in contrast to the metal casing is completely, which gives a solid impression. During the warranty period - about 7 months, the unit was old - it was broken, that is, the fan has stopped running and therefore the device is switched off because of overheating of himself and showed through the red light a fault. When the device hardware store was posted and it took about 5 weeks until I got a new device. Why does the unit has not been repaired, I was not yet clear. After the warranty period had expired, the same error occurred again. This time I opened the unit, which was already difficult enough alone because of the plugs with the stupid triangle. Therefore, I have the most simple screws drilled and wanted to replace it later integrated screws, for which however still not arrived. After opening the device a loveless processing and the use appeared inside quite expensive items. In addition, should be selected for the power supply cord, a larger cross-section. Fairly quickly I found that really only the motor of the fan was broken. Now I was hoping for a spare part, which was not to procure the first dealer. The second - even a flat rate of 50 Elektrofachbetrieb- wanted already for nachgucken and open, even though I had pointed out that this was already done by me. This package would always rise and also must not necessarily the fan is defective; Finally, I was a layman. Trying to get a replacement over the Internet, also went into the void. Now the open device is already with me around for a year and I hope to come across someone who can get a comparable fan or at least the engine to sometime. Then this heater would run again. Maybe I'll buy again a, reject any warranty and let me instead a fan - or even better, two - designed as a spare part. Then I would certainly enjoy using this device. What a pity that apparently only to be sold and after two years - the end of the warranty period - Taking the good piece simply for electronic waste. I would honestly prefer a heater that would hold for 10 years and run smoothly. But such is available in our fast-paced then probably not.
