As a marathon runner, tracking hydration is crucial. This device makes it effortless. Battery life is amazing - I charge it once a month. Highly recommend!
1 month agoGreat product, minor issue
Love the concept and it works great! Only issue is it doesn't fit my Contigo bottle without the adapter ring, but that's included so no big deal. The app is beautiful and intuitive.
