I have now conducted an exhaustive trial of the new, although it it's not actually new, "Probasics Stealth" pillows mask. I'm not submitting this to our formal "review" threads because I feel one should spend a bit more time with a mask than I have with this one before making a final judgement. The mask looks interesting when it comes out of the baggie. I actually had 5 sets of pillows to choose from: 1 large, 2 medium, a small, and a ridiculously small. In addition to which the pillows can pop off the little frame thingies and are therefore interchangeable with any of the other frame thingies. That provides for -- let me think: 4 different mask holder thingies, times 4 different pillow sizes of which one or two can be swapped to the other mask thingie.......... That's 1 1/2 plethora of options. Enough to accommodate even the most persnickety of nosies I think.
I like the straps. If I could, I would retrofit them to a P10 and send them to Paula. That way when she finally sees the light and converts to the P10 she'll be happier with the straps. No need though: she'll come around anyhow. Resistance is futile.
Assembly was straight-forward and intuitive. Then, once put together, I took the whole thing apart and did it the way they thought it should be done.
Finally it came time for the true test. I hoped this mask might let me forgo my chinstrap. I don't even know why I thought that. But it made sense at the time. Anyhow, masked up I pushed the cute little button on my S9 and air began to gently flow. All through the room. Into my eyes and ears and hair and socks. Just not into my nose. I could no longer here the television because of the airflow. The puppies began to bark excitedly.
My successful test concluded, I turned off the cute little button on my S9, disconnected the mask, and threw it across the room where it became an instant pull toy for the puppies. So all in all, I would say a success.
I put my P10 back on and went to sleep.
End of review.
