my PATH®

Does not accurately log refills as it takes a lot of time to "listen" for water sounds. Shaking bottle forever and never "heard" water sound. Had to go to a quiet room to avoid background noise. Also made same water sounds with another drink in a plastic cup. Can shake same or different water container to get it to "log" refills. Not worth the efforts, when you don't have the time to shake it just right to get the effect, or just fake it out when you forget the bottle.
