I really like this pillow. It is supportive for both back and side sleeping. I've had fewer neck issues since I got it. My wife also says I'm snoring less.
Some issues to consider: It is crazy heavy. It took two days to air out the funky chemical smell enough to use it after opening the bag (and about a week until it went away completely). The "cooling" isn't super noticeable.
Overall, a good pillow for the price. I'd get it again.
