Much cheaper than replacement cushions
I have very oily skin, and had to wash my cushion daily and change it monthly or it wouldn't seal. I thought I would try these to see if they would help. So far they are working well, there is a bit of air leakage and I have to have the straps tighter, but there is none of the annoying noise associated with the leakage. I also haven't had the skin irritation I sometimes get with the silicone cushions. They seem like a less expensive alternative to changing my expensive cushions. My only criticism is that they are not custom made to a particular mask, and that the opening must be hand cut. It would be nice if they would custom make them to fit the popular masks.
