200mg of caffine and tastes great.

Not a bad flavor just not watermelon flavor. It tastes almost exactly like a cucumber energy drink instead. Rebrand it to cucumber summer slam or something. Tastes nothing like watermelon though.

One of the best tasting energy drinks I've had! Gives me energy without the gutters or the crash like some others I've tried. Will order again!

Hard to find in stores now. Glad it's on Amazon. Great taste and gives me energy without the side effects.

This is more of a fresh watermelon flavor than a candy. Watermelon flavor is so many other energy drinks are. The ingredients are straightforward. I do feel like I was more focused and it is fairly good value for the money. No sugar or respectable amount of caffeine and it was very effective.
