I use the N20 and am considering the F20. The other reviewer has obviously never used either device. To counter his review I'm going to give this 5 stars... Again I use the N20 with the magnets and LOVE IT! Set it once and forget it, you don't have to adjust every night!
As to magnets and health. There has been no proof either way on that BUT if it matters, I haven't noticed any negative affects with my N20.
But if you are still not into that sort of thing just avoid this mask as it does have magnets, but, don't negatively review something you have never used just because! That is ignorant...

This mask has magnets. I can't believe wearing magnets this close to your face for 8 hours is a healthy thing to do.
