Very good Isolierflasche

I have the bottle to use for about 3 weeks in daily. The insulation properties are truly outstanding, even half-filled the Soaked remains many hours hot (not warm).
Provided they are flushed before the actual fill with hot water, which you should do but in all flasks.
The shipping and packaging were also quickly and neatly.

Only the quick closure has gone me after about 15 days break. He snapped no longer in the position to be able to pour a drink at the, therefore only 4 out of 5 stars.
I wrote an email to the seller and asked for a replacement lock. After less than an hour I supply a free replacement lock was assured. Top Service of 4Tools.
