I'm a bit skeptical after doing some reading on these kinds of programs. I no doubt believe they make a person more fluent over the course of the program, and shortly afterwards, but you can't change lifelong habits over the course of a week. Apparently, many stutters complain they revert back to old habits sooner than later, and now they are a thousand dollars poorer. Don't want to discourage anyone, but long-term mileage will vary greatly.
