Hello, Very surprised! Very suspicious given the price, I have bought 2. (Of the 2 there may be one that will work properly). Control with an electronic thermometer in the oven temperature to 180 degrees Celsius: indicates a 120 degree Celcius The other says 130 degrees Celsius. Product that comes from China with free shipping, how do they Am Stadtpark Chinese !!!!!!!!! Good day and good apetite, but watch your cooking. Purchase for both EURO LESS ........... 4 How they do these Chinese !!!!!!!!!! PS: J tried again another time, 160 degree oven Play 190 and 200 degrees. CONCLUSION: If the cake is white ..... c is undercooked, if it is black ..... c is burned. I leave my wife continue to cook.
