After reading some reviews here, I was a bit skeptical about whether I would be, for example, also disrupt "the metal noise" while pressing down. So the sound is only 1x, in brand new Condition-- without coffee. Anyway, in my pot ;-). After 20 years of gambling, whether the vitreous healing comes from the dishwasher or anyone zerdeppert the thing accidentally, I am completely satisfied to have discovered this pot. Would I buy again at any time.
PS They should not be confused with the milk jug and place on the stove, otherwise the bottom bulges slightly and the pot looks a bit singed the gas flame .... But still holds ^^.
