This is a good product. The reason I gave it three stars is because it's a little "loud" and the protector "crunches" as you use it. Also, it insulates the pillows a little too well, so it may take a second for the pillow to deflate to a comfortable height. This is my first time buying a pillow protector so perhaps this is how all pillow protectors work. The fact that it's so air tight, I don't use the pillow protectors on my pillows but rather the guest pillows.
