I ordered this thermos and simultaneously bought the same model (same brand, same capacity) in supermarkets (much cheaper). I thought it was the same models, but the one bought in supermarkets has a more sophisticated plug that allows faster opening to serve. However, I prefer the model presented here because the automatic cap seems to be less hygienic and more fragile. In summary a good model; The cap does not leak and does not need to be highly secure. 4 stars because the ride is short enough hot especially when the liquid is already started. Count half a day. Good for the morning coffee.
