Has anyone else started noticing that the F20 headgear has been losing its quality lately? I have patients who come in nearly every 8 months to purchase a new headgear strap... and for the retail price it is purchased at, it is quite steep.

Would love to hear anyone else's opinion on this issue

could be a few things: - strapping too tight? - magnets causing issues if you have any type of metal in your mouth such as fillings, dentures etc. - positioning of upper strap too far back The f20 is known for causing sores ontop of the nose, especially with the silicone not having much cushion. try...
