It is never a good idea to fund companies by purchasing software that is still in pre-release (beta) stages of development.
Wait for the actual release and wait for some reviews to come out before you make a purchase of this magnitude.
Be wary of marketing write-ups like the above that look like they were written by someone in Kashmir - full of grammatical and spelling mistakes; the actual code may be as badly written as the hype.
Sounds like a product line of years ago, called "Miracle." The marketing hype stated: "If it works, it's a Miracle." Same here perhaps? If it works, it's Stellar?
