Not sure about version 1, but I'm testing version 2 right now and I have to say it's the best auto spinner I've seen bar none. The content is actually extremely readable and probably better than the manual spins a lot of people do out there. However, some of the content doesn't pass copyscape so make sure you play around with the settings. Minor edits should do the trick. I'm on the trial now but seriously thinking of keeping the Turing plan for my Tier 1 content.
A website with lots of unique and human-readable content is going to give you the best ROI. The more quality readable content your website has, the more exposure it will get from major search engines such as Google & Yahoo. But creating unique content takes time as you first need to develop content creation strategies and then you need some hours to write a full SEO optimized content. How great it would be if you can produce quality content within minutes! Yes, it's possible with the help of this free Article Rewriter Tool developed by SeoToolStation.
