“Excellent product and excellent customer service. I was sceptical about this item but I had been encouraged to buy it by a family member who was hugely enthusiastic and she was right. It does help you to sleep better, it has eliminated my husband's snoring and relieved his sinuses, I use an inhaler to help with chest problems and I find I'm sleeping much better and my husband says I no longer sound like I'm drowning in my sleep. So whatever the science is behind it I am happy to say it's working for us and I would definitely recommend it to anyone with similar respiratory issues”
