Amazing product for Energy top up , taste like Classic only with No sugar , it is Effective but i wouldnt recommended on daily basis as it can crush your health, time to time Amazing

It's great that red bull do a sugar free version but for me it just did not taste as good as the real thing, it was ok but if you want an energy hit then you need to drink regular red bull. It's not terrible but not quite as nice.

These are great. I prefer getting sugar free so I feel less guilty. I only get these when I'm having those sluggish kind of days and it's a little pick me up. I think these are better than the full fat ones. The taste is amazing!

Great taste for being a sugar free energy drink, very similar taste to the original red bull. I love the original red bull and this is an excellent alternative when looking for a sugar free option!

This is deadly sweet. It's literally sugar in soda and if you're on a diet, this is the last thing you should be consuming. The ingredients are awful.

Tastes amazing! I actually prefer the sugar free version. It gives me a quick energy kick so definitely effective. I love the packaging being lighter in colour - makes complete sense.

This red bull is great for energy and being diabetic it doesn't affect my sugars that much. When I'm feeling tired this is my go to for an instant hit of energy. To me the taste is the same as the original just not as sweet

I tried this before and I didn't really like the taste. Without sugar it almost taste weak. I don't get any energy from any energy drinks either. But it works for everyone else around me but they prefer with sugar.

Gives you wings great taste reasonably priced helps with energy levels before sports or just general day to day tiredness I love the taste of it and it's sugar free

Great tasting energy drink! I tend to buy these one at a time as a pick me on a long day when i need to stay focused. I prefer the taste of the sugar free version.
