Time is money. If you don't understand that now, you never will. I think mine is a fair request.
Naturally, time is money, but you have to recognize that profitability is what makes time valuable. It's not the time itself, but what you can do, and are doing, with it.
And if you come across a tool that is offered to you at no cost, and all you really have to do to learn to use it is watch a video (or even just "listen" to it while doing other things ... which is what I did), then I'd say that doing so, and testing the tool out, could be a very valuable use of your time, thus making that time "money." Completely worthwhile, I'd say!
Some of the biggest marketers out there invest significant time, effort, and money into R&D. They're always looking for good, profitable moves to make. Usually, what they find is not something that can be immensely valuable to them, but when they do find it, they know how to maximize the hell out of it, thus making all that time searching and studying, and coming up empty, worthwhile.
Mark Warren once told me, "If you're not failing, you're not trying hard enough." If you watch the video, tinker with the tool, and you fail to find something useful in it, maybe you've lost some money on that (money = time), but it has taught you that there is one less thing out there on the market to focus one iota of your attention toward. Thing is, you can't know that until you check it out for yourself, as unless you're paying a team to do your research for you, it's up to you to determine if the tool would be helpful to you.
Squark was more than helpful enough to let this be tested at no cost. It's up to us to take responsibility for making ourselves money, and that involves doing our own research. Nobody else is going to do that for us, and that's the way it should be.
