With this coffee every morning while drinking my coffee I tell myself that my husband is a genius! Seeing what state I was in despair after breaking a 3rd glass coffee in less than a year, it was he who suggested I take one in stainless steel. I was a little hesitant because it was still a price therefore for such a small object, but to watch now I think that ... 1) even me and my left hands we are not going to break this pattern! 2) it is pretty when she hangs in my kitchen (it has already been admired by my mother and my stepmother!) 3) it can be cleaned in less than two. Flushed a little under water is great ... it is clean lining. 4) the coffee is great, no difference with another classic coffee. I do not say it holds the heat longer. But that is a detail compared to all the qualities she has. If you really want a bottle "thermos", it is perhaps better to choose something else. I highly recommend.
