Congratulations! By now you have also posted on wearing it successfully at least one night, so double congratulations.
Like Al Gore inventing the Internet, I invented the P10
Seriously, for those who CAN wear it the P10 is typically miles ahead of any other mask, or at worst as good as any available.

The diffuser/vent doesn't seem to have a heck of a lot of air flow compared to the Philips/Respironics Wisp mask I'm using. Does it really allow all the CO2 to bleed out?
First, the P10 has such a SMALL internal volume that there is very little dead air space to worry about; likely none compared to your own lungs, breathing track, and residual volume.
Second, the P10 is venting, they have just found a way to make it so diffuse and quiet that many times we have trouble telling the machine is even turned on or pumping air.

The Resmed machines (S9 etc.) attempt to SUBTRACT out "mask leak" from total leak to report the final "leak number".
The different mask types allow for more accurate adjustment of this figure. Ideally, (if extreme accuracy were important) there would be a setting for each and every mask type down to the model.
But since the major types of masks sealing to the face (FFM, NM) or just pillows in your nose covers the largest discrepancies the simple settings seem sufficient.
For a 'Hybrid' (oral mask with nasal pillows), I just have to guess which is a better fit.
This is only truly important when comparing your leak numbers, e.g., when using the 24 l/m as a cutoff for "good leak vs. bad leak".
Truth is, *I* want my leak numbers WAY below this artificial limit anyway.

No, the ones I have link in *my* posts work well. I have tried the PASTE (way heavier than a cream) and the liquid.
[search for 'lanolin' in posts from 'HerbM' to find the references, perhaps adding Amazon to the search terms.]
Both have uses, but the liquid is best for something like your lips where you want a large area of spreadable coverage. I prefer the paste for spot protection like contact irritation from the mask.
Generally the irritation is from one or both of the following sources:
1) Wearing the mask TOO tight
2) Allowing the mask to 'move' around or putting the mask on and off or otherwise 'fiddling' with the pillows.
Wear it looser than you expect it should be.
Leave the darn thing alone and stop fiddling with it once the fit is set. (Really)
Irritation is very similar to shoe irritation and blisters; it is caused primarily by FIT, PRESSURE, and SLIPPAGE (movement) against the skin.
See my other posts about the P10, fit, putting it on carefully (e.g., in front of the mirror and do NOT adjust it ALL night), and other wearing tips.
If you are in doubt, wear it LOOSER.
