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.
I should have taken the other reviews seriously rather than trying to save a few bucks. This is not the product in the description- the Keystep is much smaller than the Keystep Pro. Not the droid I was looking for.
