It's a bit thicker than my normal wedding ring, but its also a lot lighter weight. I don't really notice the difference enough to mind. I suppose if you're not already used to wearing a ring it might take more effort to get used to.

They come in different sizes and they don't necessarily correspond to standard USA ring sizes, so it takes some effort to measure and make sure you get the right one. But the effort is worth it to get a comfortable fit. And they are cheap enough that you can always buy multiple different sizes. I think I paid like $11 for mine on Taobao with free shipping (part of that may have been a discount since I was a new customer).
