I used the speecheasy and the fluency master (prefered, less annoying). They didnt last for me. They work off the interesting principle that we typically dont stutter when speaking in unison. So what this device does is they put in an earpiece (in the case of the fluency master, also connects to a microphone which is stuck on a little bone below/behind your ear which vibrates when you speak). This creates a fake chorus effect which tricks your brain and viola, you're fluent. Its really annoying though with the Speech easy because its always on so there is a constant echo/chorus sound. The fluency master doesn't do that because it uses the microphone so you only hear it when you speak. It stopped working for me pretty quickly. I believe this is best used as a tool for important situations such as phone interviews/etc... but I couldnt use it all the time, even if it did work. If you're really done with letting your stutter run your life, then be done with it. Say Fuck it and dont give a fuck about it. Stuttering is only as bad as we feel about it. The best way to not letting to prohibit you is just to stop letting it prohibit you. But that takes a lot of want and courage.
