Snugz Mask Liners, by WakeWellReviews of sleepsnugz.com

I could not get the mask to seel. So for me it was a waste of money.

I am sure it good for who it fits but the Quattro pro full mask writing that it wont fit was small enough never saw it until i got it ... now still needing and out the $ for my mask

I was unable to get the mask to seal with the liner in place which is unfortunate because it did make it more comfortable unfortunately it is no good if it wont seal.

The Snugz does not fit the F20 mask very good. It was to tight across The nose and the bottom part didn't want to stay over the seal mask. Made for bad nights sleep.

It made it more comfortable but it also caused gaps according to my machine. No matter how tight I strapped in. It might be my mask itself, but without the pads I get a tight enough seal not to cause the red sad face on my machine

The product doesn't fit as I expected it to and so it was very uncomfortable to use

The product was poor. It creates an opening between mask and face causing air to leak. It also requires the headgear to be much tighter to compensate. I wouldn’t recommend it.
