"The bar has a great texture and crunch. It is appropriate in terms of size, and allows for multiple large bites. The flavor and chocolate taste wonderful. The ingredients come together, and it makes it seem like eating rice krispies, but with all the macros endurance athletes needs (sodium + carbs)"
"Tastes distinctively cocoa-like, but without the aftertaste of artificial sweeteners. Delicious texture, not too crumbly, but also not mushy or break-your-teeth crunchy. Just the right amount of nutrients to get you ready for a run without having to wait too long to digest. Definitely will purchase again!"
