A good product, but....
not a good match for me.  When you look at people, we all have eyes, a nose, and a mouth.  BUT!  That doesn't mean we can all use the same sized oxygen masks.  This mask is a good product, but for me, even though I am a fully mature adult, this mask is too long.  When the nose bridge segment is seated on my nose as it should be, the part that should touch my chin is hitting my neck!  Seems to me somebody should be able to come up with an easy way to set out sizes for an oxygen mask that comes closer to offering a realistic fit than "adult" and "child."  I can think of several ways, but who's going to listen to me?  Anyway, if you have "average" or "long" placement of your eyes, nose, and mouth, this oxygen mask should work just fine for you!  Good product, just not a good size for me.
