I’ve tried alarms, notification apps, and calendar reminders, none of which have worked as well as this bottle! My water intake is usually appalling, I’m lucky to take a single sip most days. This bottle has made it a challenge for me to drink to each time line, and has by far been the most effective way to get water into me. If you struggle to drink water, even with reminder notifications, I highly recommend this bottle. Plus it’s super stylish and nice to drink from too!
