I actually ordered for a birthday present, the rubber rings. Since in stores rings were sold out everywhere, I thought Order soon on Amazon. Unfortunately, the delivery time was 4 weeks, since the product has been sent from China. So the gift was too late .... To the product per se. For the price you can not complain really. They are not always without flaws, but so far but I only had a broken Ringchen for a still fairly wide range of different hues. For the money, I would order the rings again, but with the knowledge that it is not within 2 weeks with me.
