As someone who's long been looking for a way to endure drinking more water, I was very excited to find a company specifically created to solve this problem. After an initial snag (USPS having damaged my package), I received my Starter Kit and an extra box of ORO cubes for the trouble. 10/10 for customer service for sure, very well done. After washing my bottle, I lined up all the flavors on the counter to give each a try. The results were disastrous. ORO, ZEN, BOOST, YOUTH all tasted like I just dredged the Everglades, and were completely undrinkable. Only GLOW, LOVE, and FOCUS were remotely drinkable and even then, only with some additional flavor supplementation. I had high hopes for this product as I REALLY need to drink more water and simply can't abide flavorless water. But despite everything else that's excellent about the product/company from the beautiful packaging to the excellent customer service, ultimately the product fails because its mission fails. I didn't drink more water, I threw the Waterdrop water out and made some iced tea. Sadly only one star from me.
