Your reviews are fine except that when it comes to energy drinks, there isn't much about its function, kick, effect or whatever you want to call it.
Energy drinks are about the "effect" not who can make caffeine taste better by some plant syrup.

We do that because the energy "functionality" of most energy drinks is exactly that: caffeine and, in non-diet products, carbs. The levels of caffeine and carbs are typically available on our site in the Ingredients & Nutritions area.
