[This review was collected as part of a promotion.] Flavor wasn't bad with a hint of berry and nice smell but had a slight artificial aftertaste. I don't like diet sodas due to this same artificial aftertaste but if you like diet soda, you would probably be fine with this flavor. Also don't like that it has artificial dye in it (blue 1). I feel like dye is unnecessary. It is a pretty can though!

[This review was collected as part of a promotion.] Sugar-free iced vanilla berry is my new favorite! The flavor is extremely there, especially for the size of the can! In my opinion, the vanilla is the most concentrated flavor in the mix, and I love the color and packaging of the can! Very appealing! Love this newer Red Bull flavor!

[This review was collected as part of a promotion.] It's actually really good. The vanilla gives it that smooth, slightly creamy vibe and the berry adds just enough flavor to keep it interesting without being too sweet. It's super refreshing and the energy boost is clean, no crash, which I love. The only reason it's not a full 5 stars for me is there's a tiny hint of that sugar free aftertaste if you really pay attention, but overall it's still a solid go to and definitely worth trying.

[This review was collected as part of a promotion.] I wanted to try this flavor… and WOW… sooo good. It's the perfect flavor not too sweet but still enough to enjoy. It really keeps you awake, especially during a long shift at work. I love the color and the can and overall loved the drink!

[This review was collected as part of a promotion.] This Red Bull flair is so delicious it is sugar free and still has a good flavor without a bad aftertaste. The carbonation is very nice and not overpowering and the caffeine is strong without being too much.

[This review was collected as part of a promotion.] This was fantastic! The vanilla is light enough that it's not overpowering but, with the berries the sweetness of the drink is perfect. It doesn't leave a bad aftertaste and is a great drink for the summer. Highly recommend!

[This review was collected as part of a promotion.] It was sweeter than expected but also had a hint of sour it was really good it tasted like a blue raspberry slushy and i usually don't like energy drinks I usually end up giving them to my husband but this I drank all of it it was refreshing and it never lost it's flavor

[This review was collected as part of a promotion.] When I received this product, I assumed it was the normal and not the zero sugar. You can definitely taste a difference. The flavor is not as potent. I honestly was not a fan of the taste, but it still does a job of giving energy.

[This review was collected as part of a promotion.] Oh my gosh, literally the best flavor of Red Bull to come out In my opinion, you can taste the vanilla so much! I don't think I'll ever go back from drinking Red Bull, definitely five stars, the temptation to go through a case a week oh my goodness.

[This review was collected as part of a promotion.] Enjoyed this as a post-gym pick-me-up beverage. My boyfriend drinks sugar free redbull on the regular and it's not far off from that taste. Just less sour, with a floral vanilla note, and a hint more sweetness from the berry flavor. Boyfriend says it tastes similar to all the other red bull berry flavors. I like it because it tastes less acidic than regular sugar free flavor.
