Judging by their site, I think they are frauds. I personally believe that a person who wants to help people with their stutter, doesn't want to make a huge profit. Judging by their models, I'd say the materials are worth about 30 bucks MAX. Sure the software took a while to make, but it still seems weird that they price it for 2500-4000 dollars. I've had multiple techniques that helped me with my stutter for the first few days and then wear off, I suspect the same here. Sorry to maybe dissapoint you but that's just my opinion.
