Honestly the best full face mask, i use a bipap machine in high pressure, and it is the best mask from many i have tried. It is easy to use and to adjust with the dial adjuster on the forehead. Mirage quattro does not pressure my nose, i use the medium size. Edith M. Nordrhein-Westfalen Germany.

quiet mask and easy to maintain parts, thanks to the service!

I appreciate professionalism and rapid delivery, well packed product, difficult to find this price in my country
