The product was introduced at this trade-show and it was a success. However, of the hundreds of people I spoke to at the booth only one made a lasting impression that I remember ten years later. This Italian buyer comes over to get a demo. After a 20 minute presentation he asks for the price. Then he picks-up the unit and says: "8000 dollars! Why so light!".
He actually thought we were charging too much based on how light the thing was. Never mind that there was a year and a half of heavy-duty development behind it. He had a mental image of what an $8,000 product was supposed to weigh and that was the end of it.
We switched to heavier steel enclosures (cheaper too!). I couldn't count the number of times I heard people make comments about the weight corresponding in some way to the price of the product.
