Seemed promising but didn't live up to hype. Excellent customer service
I got two, for myself and my wife. She stopped using hers after a month or so because it made her neck pain worse, I stopped a few months later. It seemed great at first, keeping my head and neck aligned. But after a while, I started waking up with neck pain, which is unusual for me. It felt to me like the pillow got firmer instead of softer with use. So I tried a different pillow and found the neck pain disappeared, pretty much overnight. It's a great idea. We're all different. This pillow may work for others, just not for me. I gave an extra star for customer service trying to make it right. I would buy from them again, just not this particular product.
