I have the dilator bought for my friend who often snores, what a thing is, but so is sleeping very restless. Without the dilator often hear, as if nothing short of breath, which is very dangerous for years of course sine health. The thing fits well into his nose, visible it does not bother him and also sliding off (size M). I see a much improved, more restful sleep with him, no shortness of breath and just barely snoring. He also says that he sleeps with the thing a little better and wake up more rested. It is worthwhile to try definitely. The package contains two pieces and a small box.
