It may be a scam, or maybe not, but one thing is for sure. 60-day non-limited trial gives you a comfortable time window and all the options in the world to decide which one it is. I say, if this was a blatant ripoff, dev would make sure no one has a chance to know it by the time money's transferred to his account. But I digress. Two-month non-limited trial is not exactly what you call "buying pig in a poke". It's true.
Note to devs: By avoiding interaction and not answering customers, potential or present, feedback and questions, you are not making yourself any favors whatsoever. Rest assured, it won't help boost your sales in any way. Samples were posted in this thread, calling you out on the quality, usefulness and high pricing of your product. Are you able to provide adequate answers to these claims, while not in a defensive and insulting manner too? A lot will depend on how you handle this ugly mess of a situation happening in this thread. This is Gearslutz, this is where you present yourself as a developer and so far people been trying to leave a good impression. It works, you know.
I have a legitimate question to mods. Say, I assemble a plugin today, call it a supa-dupa authentic emulation of whatever, write an extended marketing essay on how amazingly authentic and cool it is and how it does all the magics and voodoos to one's tracks, paint a nice GUI and put a big price on it all along, BUT! Without the actual proof of my words, without the sufficient enough demo to prove it, (and surely not meaning the demo posted by the dev, it's ridiculous) why would I be allowed to post my product on Gearslutz to begin with? Does Gearslutz as a respected resource wants to be in any way related to any potential attempts of scamming Gearslutz members? Is there any quality criteria, allowing or disallowing developers to post their offerings? Because, frankly, not every dev out there provides their customers with a generous 2 months of unlimited trial. I'm not talking this particular case, as you see, but speaking in general, is there any sort of scam-proof here? Does anyone check the quality and the adequateness of the stuff posted before its posted? Some sort of quality control would sure help avoid all the drama happening in this thread, agree? Or is it a free market for all, "do as you please"?
