Just had my first night with this mask: [img][IMG]http://i1316.photobucket.com/albums/t611/jaybeem/respironics-nuance-gel-exp_zps72ed5ebe.jpg[/img]

(I have been using Swift FX for Her medium pillow for months. I love how minimalist the entire apparatus is. But I am really between the small and medium sizes, so I have been "gluing" the pillows to my nose with Mustache Sealer for Diving Masks. That works fine, but I am beginning to worry about putting that stuff in my nostrils every night, as I have no idea what is in it.)
Description: All straps are stretchy. The top strap and the straps from the gel-padded frame are adjustable. There are small, medium, and large pillows. The cones are surrounded by gel-filled pads that fit against and well beyond the outside of the nostrils. The cones that go into the nostrils are very short and very small. It has a light, stretchy, flexible hose.
1st night's sleep: About the same, except leaks were lower. All leaks were below 5 expect for a large leak when I was on my back and the back strap displaced. No change in awakenings. AHI consistent with my 1.somethings.
Cons: Nuance Pro is more bulky than the Swift FX. The Nuance Pro frame is stiff and protrudes on the sides of the pillows. I had to hang my nose further over the edge of the pillow (I am an almost-stomach sleeper). Back strap sits higher on the back of the head than the Swift FX and was easily displaced when I was briefly on my back when I was about to awaken. (I will try fiddling with straps to see if this can be improved.)
Pros: The nostril cones are so small I could not tell that I had anything in my nose. The gel pillows did not displace unless I yanked the whole mask, which I did not do during sleep. I could wrinkle my nose, scrunch my mouth, or make faces and the pillows did not leak. Much more forgiving fit. With the Swift FX, I must slide my face along the pillow and tighten up the Swift FX, as I usually have puffy eyes in spite of having the Swift FX mask properly loose. No puffy eyes or strap marks with the Nuance.
Conclusion: Mostly because I am between sizes with the Swift FX, this is a keeper. VERY comfortable, VERY stable. I rarely sleep on my back, but if I did I would be concerned about the placement of the back strap.
