Sugar freee refill is just something that made me feel alittle better about drinking a energy drink. I used to hate the taste but it's one of my favorite. The regular Red Bull is too sweet for me now.

Hands down the best low calorie energy drink. No aftertaste, which is rare. The gold standard for sugar free energy drinks. Price is in line with other quality energy drinks. Available in a variety of sizes at most locations.

I dont usually buy energy drinks since they are really bad for you and I have medical problems that make it hard to drink caffeine everyday but if i need a pick me up I only drink red bull if i cant have coffee.

This drink has a light and crisp refreshing flavor. I definitely prefer it cold over room temperature. This gives me the extra kick I need to get me through a long day.

Looking for a little pick me up at 2pm , this will help you push through the rough patch after lunch helping you excel in your job . No more feeling sleepy during that afternoon meeting were boss carries on in that drab voice.

Helps keeps me awake when I have a long night. It's not too sugary tasting and I opt for the sugar free option. Aside from the obvious artificial sugar taste, there are no issues such as jitters or facial breakouts from this.

it tastes amazing it gives me energy for the whole day. I absolutely adore this for those days where I need a boost of energy! and I love the fact that is sugar free

I prefer the sugar free kind because I actually think it tastes better. It's the perfect size where it keeps you awake but doesn't give you the shakes

Red Bull is my energy drink of choice. I especially like the sugar free because I don't need all that added sugar. Red Bull is my favorite by far I love the taste and recommend it!

Fruity, but not too sweet! Perfect replacement for my morning coffee/caffeine on hot summer mornings! No diet drink after taste. The 12 oz is my perfect size.
