that the free version of almost all the products I've tested are better than the paid versions. The only exception to this rule is Emisoft's Mamutu, but then I might say the free version of their anti-malware suite is better also, as I couldn't get reliable performance from their full paid suite. Mamutu doesn't have a free version anyway - so it is fully an exception here.

I have paid for full versions occasionally to see if they work, so I have supported many of the best tools many times; and many of my clients have too. I also encourage donations to the companies that take them, most of my clients can afford a few dollars toward the cause, and they are surprised when I recommend such small amounts - but then - if I didn't they wouldn't be able to support them anyway, as most of them are indigent.
