I got the same thing the other day. I was not happy cause it feels like light plastic but so far so good. Things I like so far. 1. dont feel like my lower jaw is pushed so hard anymore. 2. top head piece is a screw now so its not giving me forehead welts 3. air comes out quieter and is more centered...

check for ccleaner. google it and read reviews all its free and does much better then windows washer. Heres thier website http://www.ccleaner.com/
