Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
I love how long I can feel full after eating this. It's a great way for me to drink more milk, and I love the chew of the unique blend of fruits and seeds added. The Tropical one is okay. The Paleo one seems to be the stuff mixed into the oats, minus the oats. I didn't like it on its own; too much like munching the forest floor. But I added an instant oatmeal and it became the same as the regular Muesli cup.
