Product review (2 stars): May seem cheaper, but it'll cost you more than OEM in the long run because it doesn't last.
I thought these were basically OEM, so I tried two.  Admittedly, if I wrote a review within the 1st week, it would have been 5 stars - that first day, I've never had my humidifier put off so much humidity in a 24-hour period - and at first I thought the metal support was a good thing - but now I think it's to make up for a lesser quality wick that just can't stand up on its own.  It also caused a weird blue film on a few parts.  After 2 weeks of operation, this wick was hard and crusty and looked like my OEM ones do at the end of an entire winter season.  I've since replaced it with an OEM one, and 2 months later it's still going strong - way better than this one.
