Red Bull is the worst energy drink ever seen before. I have very bad experience with it. I thought it will really fill energy after drinking it. But I was wrong. its totally a bullshit. The taste is very bad. As the name is so cool the product is very less energetic. One thing is very good that is its packing. The cost is also very high as compared to other products. I will not recommend you it at all. You can try other product but not red Bull.
