So, I initially wrote a review, before hanging this shower curtain liner.
I would give this no stars.  A cheap very cheap piece of plastic.
1) The holes were punched, I had to break them open in order to hang.
2) Very thin material-4 years ago this liner would have cost 1.99.  Or better yet, I could have purchased this at the dollar store for 1.25.
3) The magnets.  Only 3.  Three magnets do not hold this liner to the tub.  I had a cloth liner with no magnets, and I am getting the same outcome.  It just blows into me.
4) What a waste of money.  Including shipping.  I threw away the packaging.  I could use it for a drop cloth.  I won't order another.
