Cup really great if the locking mechanism would be reliable ...

I join in the recession my predecessors.
I had (not Amazon) bought the cup, and in the beginning I was really pleased, the cup holds a long warm, 100% was tight, it was easy to open and close and was just the best.
Sorry, there was also with me break the shutter button, he began increasingly to shake and ended up staying just stuck in the open position. I do not know why that was, at least it worked again when allowed to stand a few days the cup. After the next use, but again the same problem. Of course that was not acceptable, so I'm waiting now for several weeks to spare at my local dealer in. Clearly EMSA has noticed the problem because the cup is currently no longer available.
We'll see how it turns out ...

Two points I admit, because otherwise the cup is really good from the handling!
