Review (4/5): Work wonderfully for smooth moving across bar.
These work perfectly for allowing the shower curtains to hand nicely and to move across the curtain rod smoothly. I would have given it a 5 star rating, but one of the hooks was broken in two at the weld area where the curtains hang from. Fortunately I did not need all the hooks and one less hook did not hurt my hanging of the curtains. I would definitely recommend these to others.
