answer:I have tried a Planitronics model, of which I don't remember which one, and didn't care for it much. Seemed a bit flimsy. I must say, and don't take this as a personal jab, that nothing , in my opinion says "goob", like someone who wears one of these things as often as they wear a watch. For driving, I can understand. For walking through the mall, babbling like the village idiot, no way.
