Not a big fan of these little guys. The idea is cute, I like the advertisements, packaging, and convenience of these, but not the flavour. I've tried almost all of them, and they don't bring much in terms of impact. I find the flavour gets really bitter if you put more than a few drops in, and if you don't put enough in it just tastes like you left juice in your glass and filled it up with water. Much rather drink regular water or crystal light or something.
