This part is just great! Since one year it is used daily by me and works just as well as a large oven, only that it will warm up more quickly. The maximum of 230 ° C, but the furnace has so much power that it acts as if they were 250 ° C. I put the oven usually 10-20 ° C would be colder than he, as this completely sufficient. A great article. For the price really too good.
