A friend recommended a Casper pillow almost 2 years ago. My wife recently said her neck hurt after sleeping, and thus I decided we needed new pillows. We've had the pillows now for about 2 weeks, and they are great. The cost is considerable (compared to a pillow you can get at a local store), but its worth it. I have no reservations, and will get another set of Casper pillows (we have two king size pillows) when the time comes to replace them.
still getting used to them. slept on feather pillows for years so these felt a bit lofty. love that they stay cool and soft with having to punch them around all the time. think they are keepers.
