Overall I love this product. I found the size I like and it works very well. The refills came in a timely manner. The whole system works great. As referenced in the instructions there is a bit of an initial learning curve on correct placement and use but its a short one. The pads hold very well all night. Don't even feel them after awhile. Clip stays on all night and holds very well. It sometimes takes a bit of effort to remove the pads in the AM but once you get a fingernail under an edge, they come right off. No pain no muss no fuss. This product is way better than the regular adhesive strips. They used to come off in the night or if they did stay on, they hurt coming off.
Now I just put one pad on each nostril, brush my teeth and by the time I am in bed, the pads are anchored. I would highly recommend and have recommended this product to those who have used regular nasal strips and are tired of them coming off or of them taking some skin off when removed. Great for campers too who cant bring along their Cpap machine.
