I was trying to up my water intake and stay hydrated. I'm a busy working mom and I often forget to drink enough water. I also don't like the taste of plain water. I tend to drink with lemon or make iced tea. The Aqua Zinger was one of my favorite purchases in 2013. My favorite recipe is a sliver of fresh ginger, slice of cucumber & lemon! Thank you for this innovative product. It's portable, easy to clean and I have not experienced any issues or leaks. Worth the investment. I would also recommend as a gift for health and fitness enthusiasts.
