Does what it says, wish it made noise
I like this concept a lot.  It does exactly what it says.  Unfortunately, I'm not looking at my water bottle much, so a blinking light isn't enough.  If I glance and see it, that works.... but I really wish it had a small beeping sound or something audible to help.  I think it would be much more successful.  I understand that would decrease battery life possibly increase cost.... but for me and my busy job, just a light isn't enough.
