All the high with none of the added sugar. It does take a while to get used to the flavor if your not accustomed to sugar free

My husband love these drinks... His go to drink when he dont have coffee in the morning.. And it actually taste good

This is a secret guilty pleasure of mine. To be honest, I  don't feel a great bolt of energy but I love having one to boost my day.

The taste is odd. I am not usually a red bull fan but occasionally you need something. This was not it. Aftertaste is bitter and not worth the jolt.

Love these! Love that they are keto approved. I do not like syrup like energy drinks and this is everything but....

Love this energy drink it tastes like cotton candy and has good carbonation but isn't too crazy for energy. No hangover or crash.

I drank this a few times. At first it was fine but then I started getting heart palpitations after consuming it so I stopped.

The sugar free is great taste just like the regular one but without all the extra sugar and calories.

Soooooo sugary and unhealthy but man is it delicious. It tastes like melted sweet tarts and was my go to during late night study sessions in college.

Love Red Bull but I don't like to drink empty calories. I love sugar free red Bull for an extra boost without the guilt!
