Product review (5 stars): Works as expected
I've ordered these many times.  They are not cheaper than ordering directly from Vornado's site but they come very quickly from Amazon.  I have noticed that the newer wicks do not last as long as the older ones do (I've been using the Vornado humidifier for about 10 years).  And, while in the past I have used off-brand wicks, the price of the off-brand ones is no longer competitive.  So, might as well use Vornado!
