I researched down pillows extensively as I needed to replace four that I already had. They are expensive so I was trying to find a deal. I read the reviews and ordered a case of these. I was very disapointed with these pillows. They flatten down too quickly and are heavy from having a pillow protector on the pillow (what would be a nice extra since a pillow protector is necessary with down pillows) but it was too much fabric and not enough down. They were too hard for what I am used to. I can't imagine that they are actually 650 fill power or else the quality of the down itself is poor. If you are used to sleeping on a good goose down pillow, you will be disappointed with this one.
