I was looking for a heater. After I read the Amazon recessions, I decided to order this. The delivery was very quick. Unfortunately, the fan was broken. I then complained about this and asked for conversion. The replacement took place quite quickly, but this fan was broken. I now do not know if both fans are from a schlechen production batch. I noticed that the fans have not been very well packaged. The fan is so packed a small bubble bag and then turn the product carton. The product carton is in a bigger carton without padding or the like. Therefore, I can well imagine that it quickly comes to damage during transport. I have now contacted the Verkäufter and asked to take back the goods and to be referred back the amount already paid.
