Im sorry you were so deceived by your "friends" Paul, but like you said, there are good doctors and Dr William Makis is one of the best out there, he takes death threats because he speaks truth. I will wait and see with TWC, one thing though, their Spike Support is too expensive, I bought 3 bottles. One thing I have learned over my life and that is, when you're dealing with a large company you pay more, its called "overhead" One example is, I had an outside AC unit put in, top of the line, my bill for everything including labour was $5,100.00 which was really cheap, I had my carpet cleaner over and we were talking about AC units, it turned out his father was ripped off by a large company, they charged him $12,000.00. So beware, you can be screwed by anyone. The one man crews are just as good if not better than the 15 or 20 man crews or "companies", do your homework before you buy anything.
