I had the kind that just hook over the rod, and I tell you I will never have that type again.
These ones are great, as they are snugly snapped on to the rod with no gaps.
For the price, these are great.
It is great quality , easy to install and to use.
Love these, my shower curtain slides super easy now!
Rusted in a month.
These are so HARD to open to get onto the shower curtain rod.
Fit on the ring but required brute force to open them enough to do so.
These are NOT rust resistant!!!
