Snugz Mask Liners, by WakeWellReviews of sleepsnugz.com

These things don’t even come close to working. They look like someone cut a couple of inches off a tube sock. I’ll stick with my regular mask.

Wouldn’t fit the mask as illustrated. Made breathing restricted. Could sleep with it on . Disappointed

Had high hopes for this product. Unfortunately, it did not work well for me at all. I could not breath through my nasal mask (get air) with the liners on. Removed and never used again. Unable to return. Waste of money. Very disappointing.

Works great. Want to order more

The product is so simply made, but it works.

Snugz provided a relaxing sleep, no worries of being woken by an air leak.

Never received item.

Great product, somewhat expensive, excellent service.
