As a first time buyer for duvet inserts, I am very pleased with this purchase!  I find that heat is quite evenly placed.  It's not smothering but I do know that it is a blanket I will immensely enjoy during Spring, Fall and Winter.  The edging was stiff but a quick wash and a few uses later it's no longer stiff.  The outer material is soft and comfortingredients like I'm hugging a pillow.  Every thing about this duvet is pretty great, I definitely recommend whether you're a first time buyer or an experienced buyer!
