The disassembly and reassembly I find OK, but where it is not nearly as easy-flaky goes out of hand, as I was out of milk bottles used to. As a milk bottle, I find the Trinkset impractical. It fits poorly in the vaporizer and easy to grip and hold bad. I will therefore use the Trinkset only as Schnabel cup and Trinkhalmbecher, but can also imagine, but to go there too "traditional" stand-alone for each purpose.
In general it is a bulbous bottle difficult to store. The Stehauffunktion works only moderately.
So nice the idea of a 3-in-1 sets is also: All in all, I have not become warm with the Trinkset.
Supplement (1/2 year later): My child refuses been drinking from this set. Only for gripping and-the-table-pounding on it is used ...
