Once again, an oval wheel

No glass insert, the bottle can withstand NEN nudge is robust. You can wash them without water between inner - and outer container from entering.. One shortcoming of the bottles with glass insert, da mal ne poetry to get purely down ... just not possible, the manufacturer can not get out. Seems to be ne spiritual and logistical impossibility.
Why the strange pouring closure is to be use, do not open up to me absolutely. If I will pour out on the closure sleeping me an arm. And I sometimes. Lasts forever. This time not to mention the mess.
Why such nonsense? Unscrew closing completely, pour out, shutter strikes .... done. If then the shutter stays tight and the flask long hot or cold, is done everything right. Is that so hard? Nothing more is needed. But also no less.
When trying to reinvent the wheel produces an egg. Congratulations! Unfortunately, this is now estimated at 90% of products like this. The stupidity attacks ever around. Get out not even a vacuum flask.
An incompetent (Power) society ... failed all along the line .... dismantled with such products itself.

That's why very well served with 3 stars.
