These are the best rings I've used in years. We've always had problems with our curtain rings catching on the shower rod, but these slide easily. My only "beef" with these rings is that they are manufactured in China. For many reasons, we really try hard to not purchase products manufactured in China. However, I was tired of searching online for simple curtain rings.
I am very pleased with the quality of this product. We've had clear shower curtains in the past, which end up looking grungy in a short amount of time. Our bathroom is very small with only one window, so we try to maximize the light as much as possible. This curtain is not clear, but still allows light to come through and also offers privacy. There is no funky off-gassing odor, and so far it has remained soap scum free. My only complaint is that it is manufactured in China. We try really hard to not purchase anything that is produced there, but I did break down on this one purchase. :(
