I have been using this liner for a while now and have had no issues so far. I have bought so many shower curtain liners- the clear plastic ones, the mildew resistant fabric ones, etc. They always get so slimy, gross and discolored within a week of using them.They never look the same and I'm constantly spending more money to buy a new one. This shower curtain liner does not discolor, it does not get gross or mildewy or anything. I highly recommend!
