Owner is a scammer who has been banned from major SEO forums for fraudulent and deceptive practices. You might be willing to look past the fact that the owner of this product creates fake accounts to post fake reviews and lies about the product if the product itself was actually good, but unfortunately Spinner Chief itself is filled with half baked buggy features (which are advertised as working completely) and can't go more than 10 minutes without crashing. All in all it is a complete waste of money and time.
And then there is the amount of time that it takes to create content with this software. I have had past experience with text spinners and although it might seem like a fast way to write content, it often isn’t! By the time you have chosen a piece of content (or multiple pieces of content to blend together), put it in the software and produced content with this software, you could instead have created content that Google loves.
