Aaron and I have been doing business together since the summer of 2012 and coincidence or not, the revenue of my business has quadrupled in this time. We recommend Spin Rewriter to all our members in our newsletter and it's been by FAR the best performing affiliate product we recommend. I think we did over $4.60 EPC with one of our earlier mailings. We've never heard of anyone requesting a refund so all in all it's really a fantastic product which sells itself.
There are some 'free' article spinners out there that require you to enter your text with properly formatted 'spintax' in order to create the end result. But how you need a totally separate tool to create this machine formatted text, so how is this really useful to you? Spinbot does all thinking for you, from taking in the context of every phrase to creating additional textual content that is as readable and meaningful as the text you originally entered.
