Vessyl's reluctance to answer questions about the sensor they are using is a big red flag for me. I'm guessing it's some kind of photospectrometer? It's hard enough to build consumer gadgets even when using off-the-shelf sensors...
The other issue is that knowing how much liquid you drink is not as interesting as knowing how dehydrated you are.

Note how they never say it "measures" the sugar in your drink. They say it recognizes that it is orange crush. I'll be interested when I can mix up a batch of sugar, water, and salt and have it tell me exactly what I've put in.
