A little sugary but does the trick to keep you moving. I love the flavor. It tastes like sweet tarts and that is my favorite part! The size is also perfect

I love this. It helps so much when you are trying to do low carb or keto. It taste just the same if not better than a regular redbull. Im not really a Celsius drinker.

I personally love this red bull sugar free drink, when im feeling down or need a boost, this is my number 1 drink. I recommend this product to any one who needs a boost of energy or needs energy when doing cardio or going to the gym.

I know these aren't super healthy, but from time to time I need a boost. Coffee and soda aren't enough so I reach for a Red Bull. It doesn't give me heart palpitations or smudging snd has a decent taste. So I'll use it from time to time as needed!

Very effective. I don't have as bad sugar crash on this version. Taste good and just like soda. Packaging is sleek and easy to hold. Compact as well.

Out of all the Redbull sizes and flavors, this sugar free is my go to energy drink. The taste is neutral and the size is perfect for a quick energy drink.

We love sugar free Red Bull. It's sharp crisp taste and great boost of energy make it my number one choice. I only wish they made more sugar free options! Great for dirty sodas too!!

Love the taste of this sugar-free option from Red Bull. It always gives me the boost of energy I need. Tastes great on it's own and even better mixed with vodka.

I was obsessed with everything about red bull, from taste to the energy it gave me, I would literally have one a day, now for health issues I can't have them! But I thought they were amazinf

I love this Red Bull because it's sugar free, I get a boost of energy that lasts for a couple hours without feeling too jittery. It's super effective!
