Some of the flavors are really good and some of the flavors are terrible. I Believe this product is giving me kidney issues because every since I started drinking from these cartridges my kidney area has been hurting. I would not waste my time in buying this product for the simple fact it is too expensive and it takes way too long to get to me. The cartridges don’t last as long as they say they do.
What needs improvement
flavors do not last as advertised (45)slow shipping (29)expensive cartridges (23)
