Now I have different opinions of Zipfizz the drink and Zipfizz the company. As a company, they have poor comunication and towards the end were downright unprofessional. As a product, I love the orange flavor, and the pink lemonade but the grape I think is nasty and I wouldn't even drink the grape when I was getting it for free. It is a healthy powder with a bunch of vitamins and it gives you a bunch of energy! Downside is that the B-12 makes me need to go pee a lot! lol I don't like how if you don't use a disposable water bottle like they advertise, you get a thick film that sticks to the side of the bottle and if you don't clean it right away it gets stuck to the bottle and it is hard to clean off. If you don't pour out enough water from the water bottle and pour in the powder sometimes you have to race with the growing foam and the lid to put the lid on before it explodes... but once you get the hang of it and mess up once, you don't let that happen again :) I love mixing the orange flavor and the pink flavor together thats my favorite!
