Sorry, not interested to sell mine. Aside from these public products, which are closer to hobbyist tools, they're experimenting with more advanced versions for people who can't move their body. There was a clip from 60 Minutes, with training the patient was able to visualize letters and get them typed onto a screen, and the host was able to pick it up quickly too. Another clip has a monkey who controls a robotic arm to feed himself. I hope they can get this tech going, it could help people. I agree, it's just a tool that maybe can give you some feedback.
