Snugz Mask Liners, by WakeWellReviews of sleepsnugz.com

Very costly for a couple pieces of thin cloth. Was still irritating around my mask. I expected material to be softer and more comfortable.

I wasn't clear on the product and got nasal rather than full mask.

Can’t breath with it on my mask.

I cannot get a good seal.

Fabric is not soft enough

I applied the cover as per the instructions but although comfortable it then broke the tightness of my seal and I was unable to get a snug seal and so got a big red face on my display

Leaks my machine show red face while using them

Can not get a fit that doesn’t allow air leaks. Every morning my machine said high air leak. Had to quit using them. Love the material but it doesn’t fit snug enough.
