Less calories with (similar) red bull taste no diet drink will be a perfect match but this come really close, i love red bull but i cant justifythe calories. Puts the sugar free pep in my step.

Best energy drink out there! Just the right amount of caffeine to get me through the day, easy to open and tastes great! Simple ingredients and it works like a charm!

I like the Taste of the sugar free and use as a pre workout before gym to give me that energy boost to get me through a workout. Classic and can't go wrong

Great taste and gave me the energy to keep going after a lack of sleep the night before and have used these when on night shifts , great packaging and colour

My fav sugar free energy drink! Easy to find at grocery stores and while on the road. Sugar free gives me less jitters and feels like a more natural boost.

this one is good, though i prefer the red bull zero sugar can, this one still gets the job done. over all, it's a refreshing caffeinated beverage that gives you a boost but doesn't leave you feeling guilty!

Love these. They have a great taste and the fact they're sugar free and still taste great is so good and such a bonus. They're really effective and priced well too.

Tastes great shocked with the ingredients. Still very effective. Great price and still same great packaging. At all your local shops so really convenient.

I love this energy drink , it tastes exactly like the one with sugar . Price is good for these days . Very delicious energy drink . It's my drink every time I feel tired .

To me these don't actually taste like they don't have sugar in them. Very sweet. I only buy on offer so always get good value for money. Just great for when I need a boost! Would recommend
