i have it! i give it a 6.5/10. my dad brought it for me it worked pretty well to begin with but like it’s kinda like a team effort?? like you have to have done speech therapy prior to using it, and i had plenty of opportunities to have FREE speech therapy but i was so fucking prideful to do it so the device doesn’t eliminate my stuttering completely. My dad uses it with work meetings and he loves it (so he’d give it a 9/10 probably, but he’s also been to intense speech therapy for years so that helped). the crappy thing about it is that it can’t be used at a loud gathering, cuz you can’t hear the feedback sooo yeah. and if you leave it on for a while, it leaves your ear kinda sore. basically it works really well with like one-on-one convos and like presentations (kinda, again practice with speech exercises). also it’s insanely expensive for a small ass ear piece. my advice is to save up money and while you’re doing that, you need to do your speech exercises (if you’ve never been to speech therapy then youtube has some tutorials as well) OH ALSO SIDE NOTE. so like i don’t really remember the process (lmao i’m 19 and got it when i was around 17 or 16) but i remember that like my dad and i had to go to a consultation where they examine your stutter and then test your stuttering the the speech easy on. and if your stuttering doesn’t really change with the device on, they recommend that you don’t buy it (I THINK). so JUST A HEADS UP it doesn’t work for all stutters.
