The Alfi Mocha TT is a good pitcher that particularly impresses by that they can be cleaned in the dishwasher. However, the first delivered jug had mentioned in other reviews error that a thermal bridge at the top of the pot occurred. As a result, maintaining the temperature for a very short time. The exchange went smoothly, with the replacement everything is fine. The pot keeps the temperature properly. Because the problem that occurred was described in other reviews, it appears to be a production / quality assurance problem with Alfi to act - since you can actually expect more for this price. Therefore, I only four stars.
My recommendation: Check the first filling with boiling water, if the upper can rim is hot. If so, directly convert.
