To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Kept making a shopping list that disappeared every time i went back to add something....you have to start over every time. It also doesn't let you add any items outside of the preprinted list. Not helpful at all!
