no more oxygen nasal prongs. check this out.

sooo is this less obtrusive then nasal prongs??
Will I look like I'm talking on a head set instead? I think I'll use this in New York, and find some sort of way to stick the tubing down...It's easy to pull off when I go into stores or we stop walking. I just really need it for the long walks in NYC. At least I'll still be getting my exercise in when we go! Also I'll be able to use this on the beach in barbados, little less inconspicuous then the nasal prongs?? Juries still out. I still have to test it out on the treadmill and see if it actually works with walking.
