I am very satisfied with this product, very cheap, no postage and delivered much earlier than the estimated date! Article very simple, but it requires nothing else to show him that the temperature I have a gas oven and it's much less accurate (at the thermostat setting), an electric oven, then it me to be done. In addition it measures only 7 cm high and 6 cm wide, it can hang on the side bars of the oven.
