First of all, hello, I am now stuck between 2 comments. In one of your comments, you said 48 hours cold and 45 hours hot. I look at your 2 comments. You said 24 hours hot and 24 hours cold. You said it keeps ice in 6 days. I wonder which one is correct. I am a long-distance driver, so the hours of heat and cold are important to me, dear. We may want coffee and tea at any time, I do not stop the vehicle and make coffee in a hurry, so the hours of heat and cold are very important to me, I ask you for a clear answer.
