The behavioral observations and product modifications I've read about in the company literature lead me to believe the trials were not a "quick demo". I also believe it's likely that they are still ongoing.
If one had been following GOSYs in-home trials closely they would know that the trials went on for almost a year, not a couple of days. Also, if one looked at the videos closely they would see at least 2 different participants and surroundings, if not more.
