Propel easily mixes with water. The grape flavor smells and tastes like any other grape drink mix. It's not my favorite, but I will drink it.
I do prefer Propel over other electrolyte beverages because it doesn't have that overwhelming salty taste.
If you mix it with a 16 ounce bottle of water, it is a much stronger flavor. I usually mix it with 20 or so ounces in a shaker bottle and it tastes more like a lightly flavored water.
The package can sometimes be hard to tear open, but that wouldn't stop me from buying Propel packets.
