The best way to prove your product’s worthiness is by demonstrating to your customers that you are willing to trust your product just as much as they should. Show us that you use, trust and love your own products first, and then we’ll consider purchasing them, also.
While this concept is mainly used in security-related campaigns, the idea can and should be used for other products, as well. There are only so many more times I can see this concept being used for security services (despite it being highly effective for this industry), but if I saw the owner of Buckley’s drink his own awful tasting medicine.. well, that could get interesting.
SIDE NOTE: It is extremely important that your product works in order to pull off this campaign 😉
