Dont waiste your $$$
Makes no sense. Everytime anyone walked bye it, it would flash??? There are times i was not near the water bottle for hours so how can i be reminded to drink. U need to physically be with the water at all times to be notified, which for someone like me is impossible. So I set a reminder to beap on my phone every hour instead. That def lets me know its time to drink water.
