Love it! It has helped so much with my positional apnea. My numbers are so much better on my sleep tracker as well as my snore app. I haven't used it in conjunction with my CPAP yet(still waiting for my mask) but my MD has reset the machine to a really low number so I think I will be able to tolerate this time. This non compliance has been going on for the past 13 years, because I was never diagnosed with positional apnea till I retested last month, Thank you Night Shift
