As a Rockstar addict I can definitely say I will not be switching to this ever . I tried this in a wal mart where they were sampling it and they told me all about how it had so many more vitamins than Rockstar and all that but I like how rockstar tastes and im not in it for the vitamins so that didnt matter to me. I tried the orange flavor and to be quite honest I found it kind of gross. Like kool aid with not enough sugar. It is kind of pricey as well and I didnt feel any difference after drinking it. I wouldnt buy or recommend this product personally but I'd suggest trying it for yourself as everyone has different tastes.
