For months in operation - first signs of wear, but ok.

A not cheap bottle which is open daily in the school use. Child-free closure, the tea keeps you warm and can be filled easily and also clean. Unfortunately dissolves despite alleged dishwasher strength gradually in some places the paint. Therefore, for the high price only three stars.

Update 19/03/2015: reduce Had the vote of 3 to 2 stars. In December 2014, the bottle ran out in the satchel. The reason was a defect in the drinking valve. So for good money, a new cap / valve ordered. This cost almost. 8 After 2 months, unfortunately, the same thing: Leaky bottle, pouring tea in the satchel. The product is not recommended for me. For a brand-name product you like puts down some extra money - if it was because then fulfill its purpose reliable.
