The cup keeps you warm and is also first tight. But ... If you have not used the cup once a couple of weeks and has only drunk from cups of coffee, it is noticeable that the coffee from the cup a strange connotation (rubber / plastic?). Whether that is so healthy ... Additionally, I have to cover once in freshly boiled water "loaded" so that the coffee dirt neatly soaks and is clean. However, this has the plastic do not tolerate: the parts are bent and the lid not closed properly. In a "thermo cup" I would have expected a little more heat resistance the plastic. Although I can turn back with the same procedure again, but I would have expected more for the price. Again I would not buy it.
