To the best of my knowledge, while the company has various secrets, none of them would be particularly embarassing. We wouldn't bother buying one of these services in advance of having a problem.

In my experience, the vast majority of salescritters making cold calls don't know much about the product that they are selling. They have about three paragraphs of information at their fingertips, and that's it. They often don't know whether it runs as a service or as delivered software, what operating systems it uses or can support, and in many cases they don't understand what it does or why someone would want to buy it.
