The finish on these is very nice and they are substantial.  And a delight to use instead of the usual half-loop over the rail type.  The reason for the 4 star rating is that the edges of the opening where you insert the curtain are a bit rough, and I did end up snagging my shower curtain in one place.  Not horrible, but it made it tricky to get them on.  As well, a few of these were pretty stiff to open and get the curtain on them, which made it annoying with my arthritic hands.  Overall, though, if you get past those two issues, these are nice, heavy weight and attractive.

Pros: nice finish, heavyweight 
Cons: edges of the opening tend to be rough, some of the rings were very difficult to get open
