Love, love padacheek mask liners....
I have 3 hybrids all with padacheek liners
I have 2 quattros both with padacheek liners and a leak strap
I now have just ordered a liner and mask strap covers for my wisp
I do sew so have made mask strap covers for all of my masks and hose covers out of comfy fleece just like Padacheeks.
Karen (owner of Padacheek) is a long time member here and helps us with items to make life with cpap much easier to live with.
Her mask liners reduce the amount of leaks from a mask, plus those of us that can't stand silicone against our skin it acts as a barrier. Her mask strap covers keep the straps from making marks on our face. Her hose covers help with rainout and is much more comfy than having a cold hose against your body.
If you are having any kind of trouble with a specific mask and don't see it on her website, she will work with you to make whatever you need to make your cpap experience easier.
There you have it..... a definitive opinion... and... its padacheek.com not pad-a-cheek
