Yes I just bought a fluency device from 'speak for less'. They are cheaper than Speecheasy and same sort of thing. I believe they just have the delay time/daf and not also the pitch change/faf. Anyway, I've been using the DAF apps for years but just occasionally. Maybe I'll use an AirPod to help speak fluently when im nervous and not in a conversation. I see a lot of people saying they wear off but I have been using the DAF app for 5 years and it still works for me. I guess if you use it too much all the time then it wears off...
