Hmmm, I wish I could 'test' one out before buying it and giving it a shot. I have perfect control over my stutter for limited periods of time, a perfect and flawless fluency with my methods. But, I can't talk all day doing that otherwise my head would explode. I was considering getting it and only wearing it while at work since I deal with people a lot. I thought maybe it would provide me with a reprieve from controlling my stammer all day, sort of a "let my guard down for a while" type of thing.
