not comfortable and don't stay in place
I have a small face and my husbands face is large, they didn't work well for either of us.  Didn't fit the mask and didn't stay in place, therefore not comfortable.  I gave most of them away and several people I gave them to liked them.  That's why I gave 3 stars, obviously not total duds, but didn't work for us.
Rating: 3 stars
