Waste of raw materials ...

... The insulation performance of these so-called "vacuum flask" is at the level of a Pabierblatt's.
Even when pouring hot liquids, the bottle is outside so hot that they can handle any more.
Unfortunately, I have only now Genome numbers the bottle in operation, too late to be returned to them. A case for the bin !!!
Who trozdem buys the bottle, immediately testing - if it is hot outside, immediately return and buy for a few euros more something better. (Eg Primus, ...)
