. had bad sleeping quality because of stuffy nose for years. Before I got Core300, I didn't expect anything happen but have a try. The first night, I felt the difference. I woke up in the morning with one nose hole stuffed only. I feel life is getting beautiful.So I think this product does help to improve the life quality. Today, I researched all details about this product and will put it closer to bed. I believe will get even better result!if you are in the same shoes with me, I suggest have a try.
