You will enjoy the device. I ordered mine recently as well and am very happy with it.
The device works so well at a distance that it actually got me in trouble the other day. I had left the SC1A running at home with a long scriipt of hookworm frequencies, while I was on the commuter train to work. Before the ride was over I started feeling very bad stomach pain and as soon as I got off the train I had to race to the bathroom before it was too late. I won't go into details but let's just say I had an interesting bowel movement.
(To those who still doubt the machine, let me just note that before I got the device, I suffered from chronic constipation and IBS. Now I almost can't get to the bathroom quickly enough!)
