I have one. I got it in 2023. It helped a tiny bit, plus it was like an emotional support for me just having it in my ear. However, using it in noisy settings was the worse. I used mine for probably a year, then I finally decided to do speech therapy. I’m a speech therapist myself and I was very hesitant to go because I felt like what could he/she teach me that I already didn’t know. I found a speech therapist that specialized in stuttering therapy, and it changed my life. I paid I believe 4k for mine I put 1k down and financed the rest. I just paid my last payment this month on it . I currently do not use mine. In my opinion if you just have 4k to spend go for it. It did help but not drastically.
