I’ve used the Smart Nora for a year and I use an app called sleep cycle to track my snoring and sleep movements. I can tell you since using the Smart Nora I have do not wake up with head aches from lack of oxygen, like I used to. I have reduced the snoring according to the sleep app by 70% and my throat doesn’t really hurt like it used to upon waking. I also noticed that before I used the Smart Nora I would jerk my legs once in a while in the middle of my sleep and wake up which I’m assuming my body sensed by lack of breathing and involentarily trying to make me wake up to breath, this hasnt happened since using the Smart Nora. I also do feel less sleepy during the day from the better quality of sleep with this device.
The Sleep Nora device is worth every penny, it’s not hype it’s a real product that works!
