I use this thermos for coffee / tea and to take on the work. I transported in a bicycle bag on my bike So the coffee / tea remains for several hours hot to very hot. 'm very happy with it. Only the resistance (ie, the so?) Of the bottle does not convince me 100%; it happens sometimes that something (really very little) has emerged in the lid. But is possibly also to the holbrigen ways that I take the bike to work. Overall, I find the bottle well to very well and would buy again.
