I bought the pure sleep, I hated it, felt like I had a brick in my mouth all night. So I tossed it (stupidly I may add, instead of returning)
What ended up working for me was buying a ObusForme pillow. It worked like a charm and was $35. Ya it isn't the most comfortable pillow but you get used to it, and I think it keeps the airway open and that was my problem. I don't think I have Apnea however.

Might be worth a shot to some people who have airway blocked snoring a try. It has worked well for me for the last 6 months. A bonus is it corrects your posture sleeping so I get less back soreness when I wake up too.
