Great "whey" to add more protein

I just came across a whey isolate protein powder that you add to individual sized water bottles.  It's called ProteinPak 2 Go.  Each pack has 10 grams and they come in interesting flavors.  I have tried the Pomegranate Fruit and it was pretty darned good and refreshing.  I realize 10 grams is not a lot, but if you add it to each bottle of water you drink, it could really up your protein intake over the day.   Has anyone tried it?
