Well, that's certainly a weird angle I got on my hand. Anyways, I'm always happy to find a new flavour of energy drink, especially if it's a sugar free one. Relentless have delivered in both respects with this "Mango Ultra" variety. I'm not sure how removing the sugar earns it the name "Ultra", surely the ultra version should feature even more of everything. But it's not the "Ultra" that drew me in, it's the "Mango". Tropical flavours are definitely my thing, and I was interested to see how they could pull it off, especially with no sugar.
It's actually not that bad. The mango flavour is certainly overwhelming, and very sweet, with that definite hint of sweetener behind it. But by using mango as the flavouring I don't think it comes off too badly. There's a bit of a funky aftertaste, but it's comparable to that kind of chalky texture you get after eating fresh mango. The closest thing I could compare this to is Tesco's mango liquorice that was around a while back. So while it's a sickly drink for sure, I certainly didn't mind it. They've done a good job with the mango flavour, despite the entire can containing 10 calories. I'm sure some people won't find it to their liking, but I enjoyed it. This is not a perfect energy drink, but it's a nice, tasty flavour that lends a bit of variety to the sugar free section.
My rating: 4/5
