The developer was also very secretive about how it worked as he was scared someone would copy it and release a clone. It was impossible for the longest time (when the price was actually much higher than it is now) to find out how the thing actually worked.

Much of this was because there was no white paper or documentation, and when pressed for details beyond the most basic, the developer just told you to read the source code once he open-sourced it.

It was bad, but it's drastically better now. The main developer changed from what was probably your last look.
