This cup, we can safely recommend. Thermos is an American manufacturer. The product comes as almost anything but Chinese. Thermos advertises that it is BPA free. The drinks in the cup stay up all night on fresh despite room temperature.
Our son is 20 months old and holds the cup still on the handles. There are larger models that we will certainly establish later.
The cup is inside a piece of stainless steel (without seams, etc.). The Henkel is placed in the open state and can be rotated. The yellow beak piece and another piece of plastic to be plugged into the blue plastic cover. and thus fixed by screw. So everything can be very easy to clean. It makes a very stable impression and has already survived a few crashes with no dents or damage.
