The experience with this supplier was very good and pleasant. One ring arrived with a small, but acceptable, defect. What I DO NOT recommend is the UPS package delivery service. I paid for shipping when I purchased the product, but when it arrived, I not only had to pay import taxes, which I consider acceptable, but also an additional $18 to UPS for administrative fees. In total, I had to pay an additional $43 to UPS—almost the price of the product!—plus import taxes. It's too much. I hope Alibaba suppliers offer us other options so the product price doesn't go up so much.
