would be good ...

I liked this cup very much. Although he does not really warm (about 30 min.), But he is very pleasant to use, with this special button. Nothing runs next to it and the cup is completely sealed in and of itself. You could him no problems if they were full toss in the backpack without having to worry.

Of course, there's the disadvantage that the cover is difficult to clean. But still I found this cup just great, compared to other "Isolierbechern" which are all more or less leaky and only so have a flap for opening of a "drinking hole". When driving a car is something less than optimal.

Unfortunately, the Contigo has become leaky but after 3 months. A real shame. For Amazon that falls under warranty. Will send it back and let's see if I get refunded the price.

Addendum:
Amazon has refunded without hesitation. Really the most customer-friendly company ever. Bravo.
