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.
About 35% of this product are not formed correctly and likely to fail soon. But 15% are duds, so not a bargain.
