Oh, it's usually dangerous. You're a consumer of products, I hope. If you went in to a company that's never offered a service before and they told you that you had to sign a contract for a year or two, would you sign it? You've never tried them. They've never offered the service before. As a consumer, do you really think you're going to sign that contract? I don't think so. I think you're going to say you're going to try it for a month or so and see if it works. If it does, then you're a very happy person.
So that's ridiculous.
