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 really like the goggles. My only complaint and it's not with the product...is they too big for my three year olds. I got them for photos of the kids wearing a yellow knit hat...ala minions. They are nice...just more for older children.
