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.
Ordered a medium as that's my normal size, wayyy too big I was swimming in the arms. Good quality material but just too big. Buttons are also difficult to undo which could be a fire safety hazard. Had to return them :(
