Nobody said you weren't "real" (i.e. legitimate.) We said the pictures in your advertisement weren't real, because they obviously weren't and you didn't explain why.
You're also a brand new member to this forum, and your only activity here so far has been to post this reasonably questionable advertisement.
Combined, that makes your authenticity and motives suspect by default until proven otherwise. No offense intended. That's just how the world is nowadays (and maybe before that too, lol.)
Just for general reference, the OP's price seems reasonable, but isn't exactly a steal of a deal. There are multiple new/unused AirSense 10 and 11 series AutoSet machines currently available from reputable resellers on the DotMed secondary medical equipment marketplace for $650-$750, some including 2-day shipping.
