does help with mask nose bite but does not 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 so this kind of works and it feels great if you are like me and get up at night to pee you will 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 will try hot glue the second most universal fastener
