Video on Amazon.com I'm a totally favorably impressed. Quiet, warm, small; and only 438 watts! The Slogen small but powerful is absolutely true here. The ceramic element is real class. The front grill should be as already mentioned not touch, because there could certainly cook it :-) so watch out for children and pets. If he falls over, he goes out - but a tip would forward due to the high temperatures very bad. If you turn off it, it cools well. Is the front as soon as the grid hot, it gets cold again.
In the car, I have no heater, but the ceramic heater on NEN power inverter operated at 600W. Little Friend is connected there and helps me early the cold minutes to the diesel is warm to survive and he exerts great ballet.
Conclusion: If you safely handle the device that is at the price-performance ratio is an absolute buy recommendation!
