This tastes kind of like Jolly Rancher sour apple, not quite as sour. Has more real apple taste, very good, very sweet.
The sweetest tasting I've tried.
Fruit Punch, and Grape also good.
I think Rockstar wins the best tasting energy drinks. Probably the most sugar as well, but if taste is your priority, they are good.

This flat out tastes a lot like Martinelli's Sparkling Apple Cider. I kid you not. I had a half-finished can in the fridge during Thanksgiving day when we were having family dinner and this was what i brought to the dinner table. My mom also had a bottle of Martinelli's and i poured into a champagne glass and drank it. After I was done, i poured the Rockstar Hardcore Apple into the empty glass. To my surprise, the color of the liquid was almost the same shade; just a shade darker and tasted almost the same as well! It was a little sweeter and thicker in texture due to the guarana but otherwise tasted about the same. I would say the taste between Rockstar and Martinelli's is more similar to each other than between Coke and Pepsi. I would definitely recommend this "Hardcore Apple" flavor if you are a fan of Martinelli's.

The flavor isn't the same as the ones you buy in stores separately. The color and carbonation as well does not look the same. I don't know if I got a bad batch or what happened. The taste isn't as strong as the ones from the store. The color is supposed to be almost as green as the can, but it's more of a pale color like how red bull looks when you put it in a glass. Other than that it didn't come damaged except for one can that leaked.

First of all, the drink tastes good and provide enough caffeine for my work day. Would buy again if same deal appears again in the future.
However, the packaging is bad as a lot of buyers have experience. There is no exception in my case. The plastic wrap looks like it has been cut and 4 out of 24 cans were flying around inside the box. Fortunately, only one has leaked!

This is the only energy drink that I actually love the flavor of. Unfortunately, it's very hard to find so I'm at Amazon's mercy.
Not sure why there is such erratic pricing. Last time I bought a case it was like $31, now it's $43. I'll wait until the price goes back down as I have seen if fluctuate like this before.
