I’ve been relatively pleased with the ResMed Mirage Quattro Full Face Mask, especially compared to the ResMed Ultra Mirage Full Face Mask. The Ultra was prone to breaking near the forehead piece, which can be expensive enough when one already needs to replace the headgear and the mask seal from time-to-time on both masks (and probably almost any CPAP mask).
A little over a week ago I decided to look at getting a different type of mask. I knew there was room for improvement, especially after having some bad nights. I also wanted to have at least one spare mask around. Trying to get through even one night without it would be very difficult.
