> who uses the same cup every time they pour a drink? That is my biggest (but not only) issue with this. And if both my wife and I have one, that each syncs to our own phone, now we need to keep up with which cup is whose? Too complicated. [Edit: I was not being sarcastic. Having two identical cups in the same house would make it difficult to make sure we are using the right cup each time. We already run into that problem occasionally with our Up bands.]
