Hmmm, it sounds like a mixed bag of results. Part good, part bad. I was thinking that since I thought it looked like a hearing aid, that I could just say I can't hear well out of that ear as an excuse. Sometimes I wonder if it's more of a distraction type of tool so people will focus on that rather than their stammer. It's kind of like tapping your foot intentionally, or tapping the back of your ear, to reduce your stammer.
