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 moulded this gumshield about 5 times to get it to even stay in my mouth, I needed a substitute before my dental one arrived and I couldn't play with it in. I wouldn't waste your time with this and pay for a proper fitted gumshield.
