Small enough to take down in a few sips. My go-to for a fast pick me up. I have not looked back at the sugar version ever since trying this one.

I drink sugar-free Red Bull not just for the caffeine, but also for the extra vitamin B6. Together they make me able to get myself moving.

A little expensive relative to other energy drink brands, but RedBull cannot be competed with. Amazing flavors to start your day with! Must buy

I prefer the sugar free over the regular. Gets me going and I don't crash a couple hours drinking it. My go to energy drink

Have one almost everyday!! Love all redbull but my go to flavor is definitely the sugar free. When I need a quick pick me up this does the trick!

This drink is very delicious, its flavor is sweet and pleasant. It is perfect to raise my energy in moments of fatigue. I recomend it to you.

I love this energy drink so much. With no calories and the mid day pick me up it is everything I need to get through those rough tiring days

I liked that it was sugar free but I don't believe it gave me energy or “woke me up” the taste was good and I would buy it again just for the taste

I love sugar free red bull. I don't know why but when i do treat myself to a can i have to drink it with twizzlers licorice.

This one is better than the original and the tropical one. You can't even tell that it is sugar free. It is just really good.
