Very good Insulated with great content assets. Through the rubber coating on the outside of a very good grip. Keeps contents for hours warm. The skin remains cold. Only at the top of the closure, it is slightly warm outside. The shutter can be disassembled and easy to clean in two. Even the sealing ring is easily removed. When daufschrauben you have to pay attention only to the fact that the sealing ring is also correct, otherwise one of the content is running fast over the T-shirt. The cup is properly installed but completely tight. The content assumes no foreign taste. The opening for filling is very large. One need not drink to be guided by a "drinking position" also to. Here you can blind ansetzten around his mouth.
Now for the negative points.
1. The price 35 Euro (at my request) is already more than just a steep price!
2. The closure The drinking cap deep is similarly a wing nut. Two wing for screwing. Very handy and easy to operate. Laterally this wing there are two wells. And these are nothing more than a design flaw. Namely, if the cup still full, always collects at weaning in these wells liquid. If, then unconsciously again, running one of these rest of liquid in the face. In hot tea (like me) a little painful.
Because of these two minuses I subtract a star. But anyway: A class Isolierbecher I can recommend.
