However, since these goes INSIDE your nose, I had no problems at all! They were very flexible and comfortable. I adjusted to it being in my nose a lot faster than I was expecting (it was within 15 minutes). I really felt it open up my nasal passages. They are very easy to insert, even without a mirror, which isn't true of all nasal dilators. This makes re-inserting them in the middle of the night (if you need to) much easier. The different sizes are really nice to ensure a proper fit. It also comes with a nice small carrying case that is great for storage and travel (you can only fit 2 of them in the case if you want it to securely close).
It is easy to clean after use too, and comes with 4 sizes that have duplicates (so 8 total) so you have extras if you lose one. However, I don't use the bigger ones because it doesn't fit well in my nose, (I use the second to smallest one). I could use the other ones, but they aren't as comfortable because of their size.
Overall, I am less tired when I wake up in the morning and have less dry mouth! This product is much cheaper than other alternatives but still works great! I am very happy with this product.
