Just didn’t do the job for me. Made several adjustments but still slept poorly and snored to the point of having very sore throat in the mornings. Worst part was trying to get my “guaranteed refund” if not satisfied. It’s a joke because folks in customer service think refund is only a small percentage of what you paid. My definition of refund is 100 percent. The company is disingenuous, misleading and didn’t stand behind its product as they portrayed. Avoid this company for misleading tactics p
