Snugz Mask Liners, by WakeWellReviews of sleepsnugz.com

Liner will not stay on mask more than an hour.

It works great on the leaks.

I am satisfied with the product.

I am always skeptical of getting anything off the Internet. It tends not to be what it supposed to be. So I got tired of feeling air leaking out and hit my eye. So I thought always try it one more time. It got rid of all the leakage to where I sleep better, I definitely recommend it

Extremely comfortable, however since I toss and turn all night the cloth irritated my nose to the point, I had to remove it. Not Snugz fault, I just have a huge nose.

Mask doesn't seal when I use this product. False advertising!

Although the purchasing was easy and delivery was timely I have given a 3 star rating because I think the actual product is quite average. It is soft and feels great against the skin, I have a nasal mask, but I have not been able to use it as an hour or two into sleeping it becomes very noisy and the sound wakes me and my husband. The cover would be better if it was about an inch longer so it could then fit on my mask the way it is supposed to. At the current length I cannot get it to tuck over the way it should.

They create a nice level of comfort and keep my mask in place. Amazing. Better than I thought they would be.
