I take this pot only occasionally, but this already for 1.5 years. So far, the pot has always kept the coffee warm or hot. Hot for 4 to 5 hours, when the pot is previously "preheated" with hot water. The pot is also often used for outdoor picnic. Here she has often survived in a bicycle bag so some bumpy roads. So mechanically very robust. Only the seal of the lid is not provided for such Schütteltour always 100%. So runs partly coffee between vitreous and outer shell. When filling of coffee then coffee runs down from the bottom of the pitcher out (possibly then to the trousers). This floor is only screwed, so that you can open it and clean the jug / drain. Thus it can also occasionally provide in the dishwasher, because always running water in the jug into it. But it is always nice clean. All in all a good product. Can I be happy to recommend.
