Snugz Mask Liners, by WakeWellReviews of sleepsnugz.com

Made my mask leak way too much. Do not buy this product!

The Phillips Dream Wisp nasal mask created an irritation on the bridge of my nose and I was hoping the Snugz would alleviate that issue and make the mask more comfortable to wear. The good news was that it was comfortable to wear and didn't irritate my nose. The bad news was that it didn't allow the mask to seal properly. The Snugz isn't deep enough to fit over the nasal mask without folding over the mask's seal and the elastic is so tight that it folds the seal surface of the mask and doesn't allow it to seal properly. It's a good idea, but doesn't work for my mask. If it was deeper and the elastic wasn't so tight, it might work. As it is currently designed it is worthless to me and a complete waste of $30..

Product was advertised to "Help with leaks and fit" ... Not so much. When applied according to instructions, My Mask Leaked so much it shut down thinking I was no longer wearing it. Your return policy is worst than your product. You cannot get a refund for an open package ... How else can you find out how they work?

Terribly ineffective. I had a sleep score below 80 for the 3 nights I tried to use this item due to mask leaks (I typically sore 97+ every night). Would NOT recommend this product.

Although they make the mask comfortable, the mask leaks drastically with the snugz. No matter how tight I made the mask it didn't make a difference, although a more comfortable feel than the standard pillows on my F20, it denies the mask functionality so therefore the one star is given.

The website says this fits AirTouch F20. It doesn't work right with the foam, and I was afraid I had damaged the foam when I took it off. The machine doesn't recognize that there is any seal at all. I don't feel comfortable returning it because it's been against my mouth. I'm glad it wasn't more than $30 for two. I haven't figure out what to use the fabric for instead.

Doesn't fit my mask like I thought it would, and for $30 I figured the quality of material would have been better.

Hate them, it smashes my mask down to where it does not seal.
