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.
The length of the sides of the mouthguard were too big for my mouth, and it's not easy to trim or reduce the sides safely. In short, if you play a lot of contact sport and need a mouthguard, go the extra mile and get a bespoke one ratehr than a generic mouldable one.
I read the reviews saying this was large even for an adult so decided to opt for the smaller size. My son is 14 and unfortunately it’s too small. Difficult to find one for a medium size mouth! Nicely made though.
