Thermo bottle Jannu: a good choice

Whether the bottle really keeps the contents hot for 8 hours, I could not check. In winter it is very pleasant to have when cycling something warm to drink it. If you prepare the tea in the bottle (even though it is officially approved only to 50 ° C), you can burn in external transport of the bottle to the backpack in the winter after 1.5 hours nor the mouth when drinking if you are not careful.

The tightness of the bottle I would give with 99.9%, because the few liquid (even with external transport at the backpack again) can emerge, is so low that it dries on the bottle and therefore makes no mess. In my experience with this type of bottle I'm also assuming that carbonated drinks not leak. However, if the bottle is opened by a transport Transport with movements that released carbon dioxide is certainly push up the content on the internal straw; which can not physically be prevented.

Overall, I am very satisfied (for hot drink in winter and cold drink in the summer) with my choice of this Thermos Bottle.
