Snugz Mask Liners, by WakeWellReviews of sleepsnugz.com

Difficult to put onto large mask. Moves during use.

I can still hear my machine , I thought they would block more .

Just didn't work for me.

Way to expensive for the value.

Mask machine issues …

It was comfortable but leaked badly.

It was more comfortable but it leaked more than before, so I am unable to use them.

Unfortunately I experienced a significant amount of leakage with this product. Although the material is comfortable, I would be awoken several times throughout the night with air blowing up into my eyes. When I adjusted my head gear to be a tighter fit—it was so tight—that I had facial markings that were more noticeable than before I had the liners attached. At this time, I don't think I will continue with this product and cannot recommend it anyone else.
