I'd love to give it a 5 star review but the pillow is a bit too soft for a product sold as Medium. It could be just a matter of preference though and my 4 stars are solely based on it. 
It's very well packaged and it fluffed up immediately as I opened up the packaging. It's also very well made and the quality is noticeable right away. I will likely purchase it again but the Firm ones for better support of my neck and head.
