I agree with that vision, live demonstrations are usually one of the most effective ways to connect a product with customers. Seeing a product in action eliminates many doubts that could arise only with a description or a photo, because the person better understands their real utility and, above all, how it applies in their day to day. In addition, that moment of face -to -face interaction generates trust, since the client can ask directly and obtain immediate responses without investigating on their own.
Another key point is that a live demo turns a purchase into an experience. People not only enter the store to look at products, but participate in something dynamic that leaves a positive impression. Many times, even those who did not plan to buy end up convinced to see how it works in practice. It is also an opportunity to highlight advantages over competition, since you can show details that are not transmitted in a traditional announcement.
