Disappointed
It is a very good concept that could work for adults that work at a desk with their water bottle next to them. But even though, they need to be vigilant as the device only blinks once - and if they miss it and do not drink, the device eventually shut down !<br />I think it should be refined at least with repeated blinking when the first blink is missed - or perhaps it should be a warning bip sound instead of the first blink, followed by repeated blinking after a while if the is missed.<br />This does not  work for children.
