I don't thine the power surge was the machine's fault. The only experience I have had with Baxter was last summer we spent in Wisconsin and I was doing manuals. When I got there I was not having fluid retention, but after starting with Baxter, I did. My feet looked like a squash with 5 sausages attached to it. Of course the Neph tried to tell me that I came to them that way. But I didn't. I spent most of the summer battling fluid overload. After getting back home I have very little fluid buildup. Go figger, eh?
