No one would expect you to buy it if it didn't meet your needs. That is why they give you the 30 day trial period.
But put yourself in their place, if you spent all that time and money developing a product how would you feel if everybody just stole it from you. Because technically that is exactly what it is, when a person downloads a product under a certain agreement and then decides not to live up to their end of the agreement, keeps the product continues to use it and then doesn't pay for it. Spin it anyway they want, it's stealing...
That should really strike home to most people on this forum as most of them are trying to make a living on-line. And it could just as easily happen to them and their products. I have the firm belief what goes around comes around.. it's a Karma thing.
It is a very good product and well worth the small fee they charge for the license. I am in no way associated with, or compensated by Tech Smith, i just believe in my professional opinion that they make some excellent products.
I have purchased and used many of them over the years.
