The pot is after filling with hot water hot on the outside. Thus, there is no insulation function. There is a shortage, poor material and certainly not original Alfi product !! Made in China? is printed on the underside. Since I, several jugs of Alfi use for many years, all of which are under the impression Germany and entertained for hours very hot, this pot can never be an original product. I strongly advise against purchasing. To buy this pot, I decided for the screw, because this better to keep clean than the usual with the one-handed Ausgießdeckel (inside form coverings) and this pot is spülmaschienenfest.
