Stand 12/2013: Now I wanted to give myself the cup and ordered two pieces. What a disappointment! The packaging boxes of both cups were badly stuck and fell apart on its own. In addition, a cup was barely visible, yet so dented that neither the one nor the other top fitted lid. Both lid again reported significant blemishes on (adhesive residue, scratches). The insulated bag is actually no longer part of the product. The cup is otherwise identical to my 2011 version.
I then ordered two replacement cups. When replacing cup No. 1, however were significant (!) Errors in the metal thread (like rusted), with replacement cups no. 2, a small material defect found in the rubber seal.
From the Einzelbestandeteilen it's me fortunately succeeded in putting together two fully functional cup. The defective parts I can return easily. Now I am curious what the two gifted people will say to the cups. I hope it will find no hidden problems.
Conclusion: The cups are great !! I am extremely happy with my 2011 version and can fully recommend. That have now ordered cups currently so many material problems, but is not okay! From "Monday variant" may in my view be no question. For my part, so buy recommendation, but you should allow that, if necessary, parts must be replaced.
