Taste was so light and flavour is not there Read more

It does actually say on the can that there's no skittles in the product. The fact that it's just generic skittles flavour too is a little bit of a red flag. It just generally tastes sweet and vaguely berry/fruity flavoured. This being said, I love C4 energy drinks and always enjoy trying a new flavour to keep me going through a long shift and found this to be a fun one to enjoy. People frequently were interested and asking me about this at work so I think it markets itself well. I think if it's on a reduced price it's probably worth a purchase and try. Read more

Not the best flavour - very artificial and difficult to pin down. The boost of energy is great but you can get that with any drink and so this was more to try the flavour. It's certainly drinkable but doesn't quite give that slushy flavour I was imagining. Read more

I have tasted 7 different flavours and this one is my favourite so far. Read more
