Unfortunately broke up after about 4 months already part of the internal coating of the bottle. Once I wanted to take with SIGG the warranty, they wanted to me despite photographic evidence not initially believe. I was offered instead to send in the bottle at his own expense to be examined incl. Returning to the bottle and, where appropriate, to send a similar bottle as a substitute, since the subject is not in stock.
In the theater, I then have done without and keep the bottle.
