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 find mouthguards as a rule very uncomfortable but love how easy this is to wear. Can even drink water and talk without removing it. No problems moulding it to my teeth. I was recently mildly concussed after a punch in the jaw during sparring and my teeth were undamaged. Gums slightly cut so 4.5 stars. Overall very highly recommended.
Great mouthguard!! a bit tricky to get the molding right as it cools down quickly and the white one is susceptible to looking a bit stained, but other than that it's fantastic. Easy to breathe and talk with it in
