I ordered this after learning about it here on Thingtesting. I like that the top of the curtain is fabric (because that part rarely gets dirty on a plastic liner), and that the bottom detaches. I haven't sent back for recycling yet, but getting rid of my guilt of throwing away a plastic liner is nice, and having the auto-replenishment is helpful. The liner portion is non-toxic which is also a bonus.
I don't have a particularly high shower rod, but the regular length liner barely grazes the top of my tub.
