Red Bull is always refreshing and it provides the sufficient amount of energy. Clean taste with or without the sugar. Highly recommend this for anyone that is interested in transitioning from coffee to energy drinks.

I used to drink these all the time when I was working night shift they helped me stay awake and they taste the exact same as the the ones that have sugar in them

After drinking this drink, I felt completely energized. I was super tired and my eyes were heavy from staring at screen all day, but my coworker gave me one and it made me awake in just 20 minutes. Excellent source of caffeine and delicious!

It fights fatigue and doesn't taste much worse than regular redbull, for 200+ less calories. It contains a lot of caffeine. I don't think it contains guarana or ginseng, which are things I look for in an energy drink sometimes.

Very good and it keeps me awakeand have lots and lots of energy i like it the taste of it is really good gives me a good amount of energy and doesnt make me have a bad crash at thee end

Red bull is number one for reason it gets you high and it takes you down very softly and the price tag is okay but I wish you'd just tasty at a bit better

I love having red bull on days where my coffee just wasn't enough. It gives me the extra kick of caffeine to keep me awake throughout the day. Great flavor too!

Red Bull sugar-free gives me energy and then afternoon slump I have all the time. I have been drinking this for many years and without fail it always seems to help

Im pregnant so i steer clear of energy drinks right now but I love red bull. I really miss them lol. They taste great and are so good for a quick burst of energy

This is my all time energy drink. the bubbly flavor can wake me up no matter what time it is. A little bit can go a long way. I repeatedly buy this product for energy and just for taste
