Tasty, easy to eat bundles of enegry
These have been my core source of food when cycling as they are perfect for the job. Each bar is a perfect size and contains a good balance of complex and simple carbohydrates for cycling nutrition. They give me the quick energy I need combined with some gels, and the oats keep fueling you over a longer period of time.They are very soft and squishy so they are not a chore to eat. As others have mentioned in their reviews, they can be a little tricky to open the packet so you'll want to open a few in advance if you intend on eating them on the go. The taste is really quite nice and pleasant with no funny aftertaste. The expiry date was long enough that they wont be wasted, I had around 11 months on my box.

energy on the go
Great bars for cycling you can really taste the banana more so than the fudge. I was getting at a good price at the time but now its to expensive for what it is so I cancelled my subscription.

The best on-the-go energy bar out there!
I use these products for two main purposes - 1) as an energy boost for running and other activity and 2) as a source of emergency carbs when I have a hypoglycaemic episode due to my Type I diabetes. For running and activity, these are great as they are relatively small and easy to carry in a running belt, gel pocket, etc., provide a lot of carbs for the size, and most importantly are easy to get down when on the move. They're not too chewy, dry or sticky and wash down well with water, so they make an excellent solid alternative to energy gels when in the middle of a long run. Likewise, as a source of emergency carbs they are great as they absorb quickly without spiking my blood glucose levels. Most importantly, the chocolate fudge flavour tastes AMAZING!!

Good enough for a marathon.
Good enough for a marathon.Bought the chocolate fudge as it was the best testing one for me. Really makes a difference when you are running more than 2 hours.Start eating this 45-60 minute into the exercise in small bites and I feel less drained at the 1:45- 2 hours mark with energy to spare and ready for the second bar.It is chewy but eatable without water (definitely better with water though). Very sweet- but not too sickly.I normally tear just a bit of the plastic before the run to make it easier to open the packaging later on (can get frustratingly difficult with sweating fingers when you're on the move).

Unusual confirion of Product
Box was not damaged however when i opened all the bars appeared to be out of shape/bashed/damaged. As if perhaps box had got very hot and bars started to melt. Taste wise they are fine.
