This is pretty nifty. Of course the problem is I need to carry it everywhere and empty my drinks into it for it to really work. If I have to carry it everywhere, I have to make sure it's charged. So now before I go out in the morning I have yet another device that I need to ensure is fully charged for the rest of the day.
