It may be all real!!! I am starting to worry about the differences from machine to machine! Some of those problems may well be true for certain machines and may sound ridiculous to someone who's machine isn't acting that way. As far as depth, my machine gets 9" (barely) on a silver Roosevelt (air test). But bury that same coin and I get 5". Someone else has done tests and gotten 2 or 3" more depth on a silver dime. It seems to me to be location and machine differences. I will watch the repair situation with great focus. Anyone sending their unit back that gets 6" and gets it returned at 9" will make me very happy! For now count yourselves very lucky if you get great depth, little or no iron falsing, and a smooth running monster!! For me, I will continue tweaking the controls and hope I can stumble onto some settings to at least improve my depth!
