Snugz Mask Liners, by WakeWellReviews of sleepsnugz.com

The first night I could not get the seal on my mask took of the liner and seal was fine. I thought maybe I did something wrong so I tried again left it on all night and the seal failed the machines limits and I now have a red spot on the bridge of my nose. I would like to return these for a full refund. please let me know how to proceed. Thank you Jamie Downie

Terrible product with a great design. I have used the mask liners that tape to the mask and never had a leak issue. These are so thin that unless you stay still expect a rush of air

I received the Liners and they wouldn’t fit my full face mask , so they are sitting in my draw 😟

Once on the mask it leaks like crazy unless you tighten the straps really really tight, then by that time your nasal passages are compromised . Maybe if the material was made out of smooth silk item?? But this is not a winner. And way over priced!!

It slipped off my mask back towards hose connection first night and the second .The date was a guess it happened when i received them

My husband says it didn't work. it doesn't seal properly around his nose.

Arrived very quickly but what a rip off!! 2 circles of material that resemble the cut off end of a sports sock that fit over the mask. Also compromised the seal around the mask so leaked air all night which was registered by my cpap machine and even though felt comfortable, really stopped the machine doing it’s job and made me feel very claustrophobic and short of breath which is exactly the opposite of what is supposed to happen. I took it off in the middle of the night and it was a relief when it was gone.

Still leaks tried it for three nights and has given me the lowest score ever I bought it to stop air leaking out but this does not do it
