I have had my Winx machine for about seven days, and so far I have noticed a definite improvement in the quality of my sleep. Overall, getting started with Winx was a very good experience.
I am mild with an AHI of 15; I had a video conference appointment with a sleep physician who asked me a number of questions and told me I would be a good candidate. It felt like a normal appointment, and I didn't feel pitched on the device. After that step, they sent a bite sizing wax so they would know what size of the mouthpiece to send.
It hasn't been long, but it is much better than APAP (I tried it for a while, was not comfortable for me). I will update everyone as I know more.
Bottom Line: Yes, I would recommend this to a friend
