Spin Rewriter is probably the best product in the market... I get great EPCs promoting it and, what's most important to me is that my customers actually love the product. Very low cancellation rates and practically no refund rates. All around it's a fantastic product — if it fits your business at all, then you definitely have to get on board and promote it!
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.
