OK B&Gs please give me some input!  Received my 432 last week.  Was so very excited and couldn't wait to try it out.  Did the cleaning thing and all was ready at bedtime.  Found that it was a little more comfortable than the 431, although the foam insert made it feel bulky.  Got to sleep within minutes (remember, I use sleep aids).  Was awakened with a Kansas type whirlwind from the bottom of the mask.  I called it a "chin blowout".  Tweaked the straps and back to sleep, well this pattern continued all night.  I  used it all week with the same results.  I compared it to the 431and could find little difference in the two.  Last night I dusted off the 431 and we had a wonderful reunion.  Per usual, slept all night.

I'd still like to keep trying the 432, but not to the extent of loosing sleep because of it.  Any input from 432 users?

Thankk Yall and GB!  JuJu
