We enjoyed using these pillows so much while trying out mattresses that we decided to bring two of them home.  We've only had them a couple nights, and so far so good.  Long term review this is not, but for the first week they get a 5 star rating.  They seem well made, and are really comfortable, time will tell.  They were a bit pricey, but with there was a sale on, with the second being 50% off, which helped a little.
