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’ve been using Bruxism mouth guards every night for over a decade and have tried HEAPS of different brands at all different prices. Despite having used many more expensive ones, I find these cheap boxes of four to be my favourites and have been using them exclusively for the last 18months or so. They’re super easy to mould and to trim down to fit before and during the moulding process. Even though there are two different sizes, I’m able to make use of all four just by trimming the big ones down before moulding. The cut edges are very easy to smooth away when soft. So comfortable to wear I even sometimes forget I’m still wearing them in the morning until I go to eat my breakfast (doh!). These are now my go-to guards and don’t see that changing any time soon. They’re just great.
