Review: So much better than a gel - Having tried a number of different gels (and not found any that are easy to consume and agree with my stomach, these have been a relevation. They are more like jelly cubes (for making jelly with) and are easy to eat, not sickly or sticky. Each energy chew has 2 sticks of 3, I eat a third at a time, and they are then easy to fold the packaging over and put them away while you eat. I use them for cycling and hillwalking and they're some much easier to handle than gels, allowing you to eat part and spread it out - I always ended up taking the whole gel to save on mess even if I didn't want any more. Once I've started to eat one, it gives me the energy I need to keep active, helping me to concentrate and complete the activity. They are suitable for vegans, meaning I can keep one in my rucksack in case someone in my group needs some energy, without worrying about whether they can have it. Overall, a great product that does what you hope it will do. And did I mention it's better than a gel??!
Review: Sticky hands on your bike ride? Then switch over to these chews. - If you're sick of having sticky hands on your bike rides due to energy gels then switch over to these chews. I'm a massively fan of SIS and especially their Beta Fuel range but I previously exclusively used their powder and gels. However, after a friend offered me one of these chew blocks, its unlikely that I will use gels again in the future. They're easier to eat on the go, you don't get sticky hands from the gel residue and you know you're getting every drop of carbs out of the packet unlike gels which are sometimes tricky to use. They're a similar taste to gels and I've faced no GI issues etc. 11/10 highly recommend.

### ⭐⭐⭐⭐⭐ These are the bomb
*by P***E on 5 January 2023*

I used these in training and with beta fuel drinks for a 12 hour time trial. They taste pretty good, but they are so easy to eat, no choking down like some gels. Enough flavour to be "nice" but not so much that they are acidic and cause issues (for me). They are more of a firm jelly than a chew, easier to eat than say a Blok, with no residue or bits stuck in teeth like a gummie. In a jam you can bit and swallow but I took the time to enjoy mine. The nice thing is you can eat half, put the remainder in your pocket and then finish it later. For me these work really well as part of an 80g/carb per hour nutrition strategy, no stomach issues for me but do test and build up to higher levels of intake. If it was winter you could do these and as much water as you needed, for long or more intense stuff they can be used a good way to just fill in gaps in carb intake. I plan to use these again for competition, and they are worth the money if you get at a sensible price.
