Winx worked for me for two years until I lost weight then I did not need it any longer. I really liked the fact I did not have to wear a mask.
I did have a CPAP machine and mask. I ended up not using it. So when I heard of the Winx machine and the mouthpiece.,I tried it, and it worked for the two years I needed it.
This is the truth!
Bottom Line: Yes, I would recommend this to a friend
