I sell 'em. I bought one first to try it out. The little hole in the side needs to be "tempered" with a piece of tape (Cover up some of the hole, and do so until the resistance felt feels the most like the resistance of your instrument.) before it does a good job for you.
This is a good tool, but requires discipline and a trained ear to use it. Are you a good sight-singer?
