Similar to others, the flavor is very inconsistent - some sips are sweet and flavorful, and the next are basically water. The claim that you can get 6 bottles on a "moderate" setting is COMPLETELY UNTRUE. I set it on 4 and by the third bottle I have to set it to 8 to get a little bit of flavor. Tried it with three different cartridges - all the same experience, so it wasn't some kind of fluke. Seems like too much money, inconvenience and waste (those cartridges aren't reusable) to keep buying it. Plenty of zero-sugar flavored water alternatives out there.
