If it were not for the bad Thermostats

Have a good piece for a while now, however, went with me also a thermostat broken. That, unfortunately, after the warranty. Now I can on the big board in the zero position to cook, to fry some already too hot, because I burn my flesh rather eg. Otherwise Otherwise the part is of good use and also easy to clean. The thermostats are easy to turn, (?? not intended for everyday use) with virtually no resistance. Shortly arrived, however, been adjusted.
So honestly, I have better quality of Severin expected specifically as regards the durability.
And a single case, it does not seem to be. ;-)
