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 requested a string set for a 4/4 violin but it seems I was sent a different size. I didn't even open the plastic envelops but I could see through the plastic it had a smaller gauge. Not going to use them.
