So visually this thermo cup is top! Anyone who sees him is with me, only irritated, then enthusiastically. =) However, the cup is immediately outside during the filling warm, which already times shows how "good" it is isolated ... After a short time the coffee is (was filled really hot) cold. So rather an optical gag and maybe useful if you drink it really shortly afterwards. My cup with screw cap and lens optics (no extra mouthpiece for pushing, which was not written as a weak point in previous reviews) was now the first use at least close.
