The bottle I have for over 4 days in use and am very satisfied. Very good taste good apple and lime. One can confidently fill the MLT bottle over a whole day of water, without renewing the fruit. Until the evening I have a fruity flavor water.
The only drawback: The screw cap of the insert can screw it is not so simple. Since I'm always tinkering a bit on. Sooner or later I get it but to.
