Nozovent® nasal dilator

Abstract
When the lateral walls of the nostrils are dilated with Nozovent, inhalation requires less force, thus reducing the risk of vibrations of the soft palate creating the snoring sound. There is also less need for mouth-breathing. When 17 patients were tested during 10 nights, every second night using Nozovent, the sleeping partners noted significantly less snoring these nights than during the nights without Nozovent. The patients themselves also noted significantly less dryness of the mouth when they dilated the nostrils with Nozovent, being able to avoid mouth-breathing.

I have heard good comments about Nozovent (and Breathe Rite Strips) but nothing about the others.
Nozovent says washable and reusable and may be the cheapest depending on how many uses you get.
Personally, I have tried none of them. The turbinate reduction and deviated septum surgery did a good job of giving me a nasal freeway.
