ive used it all. basically with flavored water, the first rip will taste decent, a lot more faint of a fruity or whatever flavor your drink is taste than you would expect, but it does taste a little like it. all hits after that the water is skunky, and take it from me i used to always have refrigerated bottled water so thats all i used it goes to be smelly and foul and skunky faster than normal water, and it starts to stink worse.
