Works as advertised.
Smart Nora pretty much works as advertised.  When it senses noise, it slowly inflates, then deflates back down.  The air runs absolutely quietly, so there is no problem with running noise.  The action of the pillow is gentle, comparable to the rising and falling of someone's chest while breathing.  The only noise you might hear is the &#34;crinkly&#34; sound of the bladder inflating and deflating. I have been told that the worst of my snoring has been reduced since I started using Smart Nora.
