Ideal for the sedentary
I received this as a gift and while the concept is great, it really only seems useful if you're extremely sedentary. I have a desk job, but still get up a lot, so I miss at least half of the flashing reminders. I also don't see them when the cup is in my car's cupholder, or when I'm home and doing things. If you search "water bottle hydration reminder" on Amazon, you'll find bottles that have hourly markers to help you reach a certain goal in a day; say 64oz. I think that would be more useful, and a lot more affordable. This device is cute, but not really worth the money.
