After a short training period, people using the HandsDown™ improve dramatically, then don't need the device anymore. This is possible because the device objectively measures behaviour, then instantly provides feedback, a very powerful combination for behaviour changes. Adults can finish training in as little as 18 hours. Children learn faster, and can finish in as little as 5 hours! Training must be done while preoccupied with another task, usually work or play on a screen.
