I love this duvet set. I couldn't believe it when I opened the box - no wrinkles! Because it is 100% polyester, even when you wash it, it comes out looking good. It's no fun to iron a queen or king duvet cover every time you wash it. I'll never go back to 100% cotton again. The cover is soft and smooth and feels good to the touch. The closure is a zipper - no more dealing with buttons! The insert is attached at 6 sides so it doesn't move around. It is a very well made product - hence the higher price. The insert is fine, but I prefer down, so I am going to put a down blanket inside and sew button holes to make it work with the cover. I find down comforters too heavy - a down blanket is perfect.
