Great tasting bar

These bars are filling and taste awesome! The only downside is there is too much sugar. So far fruity cereal is my favorite.

The Big-O Fruity-Peanut butter

The BIG-O bar is visually bigger than most bars in comparison. The calories are higher as well, about double on average. I brought the *fruity cereal peanut butter" Personally, the fruity cereal flavor is a lot less tasting than the more dominant peanut butter tang. This by far doesn't lower its value whatsoever The 27 grams of protein is the best one can get that I have seen overall. I give this bar and the value a high degree of 4.75 stars if I could, 5 out of 5. I recommend this product highly.
