Up until now I used a Nuance pillow mask and liked it. I tried the DreamWear mask and liked it even more. It is very comfortable and works well sleeping in most any position. I like that the hose attaches on the top and is out of the way. I also find that there is no irritation on my nose or nostrils at all. I have used it now for a couple of weeks and I'm very impressed. I highly recommend it.
