Very good! for excellent results you put it in the refrigerator 2-3 minutes before pouring cold water for it to last even longer. In a 12-hour test with cold water, it was as if it had just come out of the refrigerator!

The best thing for filter coffee that when it comes out of the coffee shop with a glass jug that does not keep the coffee hot for a long time, you put it in this warm jug and it keeps it hot much longer even than the coffee makers with stainless steel jug. Finally, the quality is very good, which means it keeps all beverages at the ideal temperature they should be. Simply PERFECT!!!!

Very good. It keeps cold water for 24 hours. The only complaint is that the mouthpiece is small and it takes a long time to fill a glass

I bought it for hot beverages and after 19 hours, when you open it, the hot water is still steaming. TEFAL quality with a 5-year warranty
