The puck of the Hidrate Spark Steel Smart Water Bottle ($70) will glow throughout the day to remind you to drink water. This feature is great for when you are sitting in one place, like at a desk. However, if you move around a lot and don't have the bottle in front of you constantly, you can miss a few glow reminders. But, no worries: with app-enabled notifications on your phone and/or smartwatch, you can still get reminders. You can customize the glow color, pattern, and frequency, all in the app. I would love to see the company add sound or alarm reminders in the updated or newer versions to help remind us to stay hydrated even if the bottle isn't in your line of sight.
