I ordered this diffuser and the same day I chopped off quite a lot of my hair, but still I can say, that this stuff is great. It's not too heavy, distributes air evenly, and because of 2 rows of long needles, you can fit even long hair in it easily.
I don't have adapter yet, so I use this diffuser on my slightly narrower Remington with help of duct tape, and I don't even mind that it's not beautiful - it works
