Try it out

It was ok, but clearly not the best bar.



The best Roeg

The best protein bar I have ever eaten!



Any time again. The best pineapple slices I know.

We are super happy with the quality. It tastes of pineapple and without the added sugar, the pineapple slices are not extremely sweet, which we both really like. They are a good snack for in between meals.

Erna the bolt

Erna tastes good, has a great consistency and is highly recommended if you like peanuts and dark chocolate. However, I also find Erna a little too sweet, just like Berta. I think it's because of the dark chocolate! Otherwise, it's also a standard in my selection of protein bars. I would be delighted if Koro were to bring out new protein bars of this quality in the future <3



Very tasty!

I am very satisfied. You can taste that it's a protein bar, but overall I think it's very tasty and I like to use it as a snack between meals when I need the power :)

Nicht meins ....

Unfortunately, I don't like it that much! The consistency is unpleasantly crumbly and dusty.
