I have a Mirage Quattro as a backup to my preferred mask which is the Quattro FX. I get a good seal with both masks and the Quattro FX isn't as big and obtrusive as the Mirage Quattro since it doesn't have the forehead support bar. For some reason with the Mirage Quattro, it puts too much pressure on the bridge of my nose, no matter what position I dial the forehead support at. I think it's because the inner more rigid silicone portion of the cushion is narrower at the top on the Mirage Quattro. The Quattro FX sits mid-bridge and the rigid portion of the silicone cushion is wider on it. I tried adding a Gecko with the Mirage Quattro, but that induced leaks where the mask transitioned from the Gecko to my face. I recently purchased a Padacheek Nosebridge Protector and that has helped, so I may give it another shot in the future. They're both very good masks, but if you get sores on the bridge of your nose from the Mirage Quattro, you might want to give the Quattro FX a try.
