I can support all the positive reviews only! Therefore, in brief: Before the first actual use I have had the part running in the large, well-ventilated kitchen an hour full speed. After about 45 minutes, no more smell was noticeable - which was not strong anyway -, "out stunken" everything. The heating of approximately 17 ° C to 22 ° C in an approximately 30 square meters (!) Large room (2.5 m ceiling height) takes on full stage about 15 minutes. I was skeptical whether this will work without a fan - previously was a fan heater in the works, but works flawlessly. Of course, silent. The casing is light and thin-walled, yet stable. The feet can be mounted easily, but for a good screw screwdriver and some force is necessary. The power cord makes a good impression; I do not feel the clear luminous rocker switch as a disadvantage. So you will not forget for occasional use in the side rooms off. The thermostat controls the desired temperature precisely.
I think the quality justifies the significantly higher price compared to many competitors. Ultimately counts the operational reliability and durability, I must therefore wait. Will report.
