Just made for traveling. Good retention+ No leaks simple system
Quite good Heat retention. The outside never get's hot , or leaks heat , better than most in this price range . Good quality, material .so less worry about failure. Good seal , doesn't leak . I have used it before 1 year. Upto expections. Keeps vapours tight . It doesn't have that drinking straw etc but that's good cuz it gives full seal and air tight. So it open with pressure which is good . Very less complains from me. So Heat retention 9/10, sealing 9.5/10 .. that's all u need .

Very Nice.
Nice quality, Value for money. NIce build quality. First you have to fill it with Hot water, then if you again fill it with hot water or coffee, it will retain hotness for more time. Otherwise it will retain for 5 hours only. Then secret comportment (middle of cap) can’t be used for storing tablets since base of cap will be hot !!

Temperature retention
Functionality Doesn’t stay as warm as other Milton flask. Easy to drink directly bcz of wide mouth but for same reason it doesn’t retain heat/cold for extended periods but good for excercise or running. Good built and otherwise
