Having a mask problem

I bought the Flexfit 432 FF. It fits great but it leaks like crazy I can tighten it loosen it and still leaks the inside
won't stay together, I hope I'm explaining this right. I have my pressure on 11, Does anyone have any ideas?

I tried it years ago and thought it was so comfortable, but never got it to be effective at all, so maybe it's just the mask and not us !

I have the 432 and I found that if the cushion is too large then I get more leaks. I use a medium or small even though the large feels more comfortable.
Also you say the "inside won't stay together".
Does this mean you are having leaks between the shell and the cushion?
If so this can be a problem with this mask. When you clean it make sure there is no soap or detergent residue left on the cushion. Any residue will "lubricate" the seal surface and allow it to separate under pressure. The cushion and shell must be "squeaky clean" in order to seal properly.
