A good product! Good grip, perfectly sealed (but think about drinking that remains between the seal and the front output overthrow or put it in a bag), by cons I agree with the other reviews: 2h GRAND Maximum warm. After it is warm / cold. This is a perfect mug for this scenario: I am at home I have to go to work or ongoing or traveling, I make my tea / coffee, I put it in the thermos, firm, put it in the bag, it's gone, and I in my car reopens occasionally drinking while driving (because it is really very practical level open / close) and if it reverses when I asked and closed, nothing flows! Or, being between two waffle prof, a small sip hot during the early hours to finish the breakfast incl. So he lost 2 stars because two hours is the maximum wide so when you put it and close it's burning and undrinkable because too hot. But not anymore. Attention for teas brewed at 75 ° C, it is in the time it takes to drink and then rinse with water at 100 ° C before putting the tea at 75 ° C for not already lose 10 ° C because of the cold walls out.
