Not only do these glide along the bar, like the curtain is weightless, because it has several tiny balls that help it along as they spin, but it also has double hooks, one on the back for the shower curtain and one on the front for the decorative curtain

I haven't had them in my shower long enough to test the anti-corrosion claim yet but I will update in a couple months

This is great, because they don't get all bunched up

And they have a money-back lifetime guarantee, so it's well worth it

They run smoothly on the rod and work really well

Very pleased overall and would definitely buy from this seller again
