Profile Lite custom fitting

Has anyone performed the custom fit procedure? I found one, but boiling it for four minutes seems excessive. I don't want to ruin a new mask!

I take it you've tried it?

Did the custom fit procedure this evening. It went very well and I can't wait to try it tonight.

I have boiled mine several times. It tends to get out of the original shape after awhile. I did boil one time to see if the "custom fit" would be better and was not happy with those results. It was indeed fitted to my face but was not air tight so to speak. It leaked all over. I boiled it again and it went back to original form and that was that.

Well, last night was great. I also added new headgear (the stock headgear was problematic) and had a very restful night. I hope it keeps up.
