The product quality is acceptable compared to the price. The ring looks good and seems to work well, but the charging case could be of higher quality. it feels slightly cheap.
They said I would receive the product within one week, but I got it almost one month after I ordered. Furthermore, they did not put the charger cable in the box. So I needed to ask them to ship it to me. Now, 16 days have passed, and I have not yet gotten the cable. They did not explain why this happened unless I asked them.
