Yum
Great flavor with less flavor fatigue. The sour is great during endurance sessions.
good flavor, not a ton of electrolytes
Overall good, tastes just like a green jolly rancher. Not great if you want carbs and electrolytes but tastes good and has a decent amount of carbs. I’ll bring 3 on a long run, so definitely can get cost prohibitive.
My favorite
Man, I thought these were maybe a bar, or something chalky. Couldn't have been more wrong. These are awesome gummy cubes. Like fruit snacks, but a better texture, a slightly bulkier shape, and way more life-restoring on a long ride. By the end of 150 km on a bicycle, these were my favorite source of calories. And sugar. And electrolytes. And sometimes caffeine!
Melted
When I received the The item melted already!!! I didn't eat it I throw it away
The strawberry lemonade is delicious
Strawberry Lemonade YES, all day! Green Apple NO- this flavor had a bitter aftertaste and not enough sour, and felt like a brick in my stomach.
Honestly really good and seem to work
As the title says, these are quite sour (I love sour candies) and I've noticed them working when I bike and run. I honestly love these chews.
Sale item with early expiration date
This should've been advertised. I would've purchased differently. Decent taste. I'm not sure if it actually works. '
Best running fuel
Best running fuel I've used to date. Absolutely delicious! Please restock soon!
Easy to use.
Easy chew while riding. Easy on the stomach. Easy on the stomach. Fair price.
