I can clearly give not advise - apart from the very high price - since the milk container smells strongly after a few days (as if the milk would be broken), the milk itself but lacking nothing !! I at least do not consume immediately after filling the pint of milk .... Thus I put the container in the refrigerator and consume the milk gradually. After 2 days is - before I again auffülle the container with fresh milk - this thoroughly cleaned .... (of course every week even with milk system cleaner)
Furthermore, is the fact that the container not only weird starts to stink, but the milk somehow changed. You can see the milk itself is not, and the milk tastes and smells normal. You will notice this but if you want to make milk froth. Immediately after filling the container with the milk all i. O., the next day also goes still, with the milk froth already is no longer so beautiful and on the second day can forget mans. Since one can speak of happiness when a milk foam still can be seen in the approach. At the milk itself not kanns are - the rest, which is still in the original packaging milk, makes a perfect milk froth. Ergo: The milk container is rubbish ....
What also bothers me: It does not look like much milk itself is still in the tank ....
