I have been using Nora Smart Snoring Solution now for almost a month and immediately from the very first night it has done what it was designed to do. It just works.
My wife is very happy with Nora and we are both sleeping much better ever since. I might have to switch to a flatter pillow since I was already using a very thick pillow to begin with, and the functionality of Nora has made me wake up with a sore neck some days, but most days are fine.
That would be my only issue with the functionality of Nora. Overall, it is simply amazing how effective and SILENT it is. The weight of my head and the weight of the foam pillow are no problem for Nora. I recommend this product to all my friends.
On an aside: the shipping was delayed through problems beyond their (the people behind Nora) control, so rather than let me wait for the shipping company to get their mess sorted out, a representative from Nora came to personally deliver a unit sitting in their office to my home. That is fantastic service and I was really impressed.
Bottom Line: Yes, I would recommend this to a friend
