Review title is Does help with mask "nose bite", but doesn't stay in place all night [SEP] The product comes with double stick tape to attach it to the mask. However the tape will not stick to the silicone mask pad (F-20). So this kind of works and it feels great. If you're like me and get up at night to pee, you'll have to re-arrange the pad under the mask while you are half-conscious. When it works, its great, and fairly priced. Need a better way to adhere it to the mask pad. Maybe I'll try hot glue? (The second most universal fastener)
