Pressed ecstasy pills are probably the best example of this. For instance, the old White Doves back in the 90's. People are reluctant to buy a press they haven't encountered before, and are more happy and willing to buy a familiar "brand" of pill. Of course, once a particular press has a reputation for quality, the fake imitation presses come in, diluting the market and eventually destroying the brand's reputation.
