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 had no difficulties with the silicone blade. The problem I had was with the construction. There are only two and not three rivets--so they didn't hold up as supplemental shapers. The company quickly refunded my money. I hope they change the manufacturing process because there's a need for these.
