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.
They’re cheap quality. I had to purchase and switch out 6mm jump rings for the 8mm jumprings they used to help with the proportions. They weren’t right and I’m sure they knew!!!! I’ve purchased a lot of inexpensive items from Amazon and nothing was as cheaply made as these. I wouldn’t recommend them.
