A deduction of points, however, I must give for the closure. Due to the resulting pressure it is not possible purely push the push-and-drink-closure and the cup must first be screwed first. This can then ever be a nuisance, so finally a mug's more for use in a hurry, if you have no time table etc.
Otherwise, I can only point out that in the lid remaining liquid when tilting more raustropft, even if the cup was already closed. This may come across as if the cup leaking - but he's not. (I do not have from the isotherm pitcher with automatic stopper known.) In addition, the cup can be filled up to the lower edge of the "dent", since the cover is very large.
All in all, a great product, but its closure should be reconsidered again.
