I received a review copy of this service from the seller, prior to the BST going live. The review copy was delivered some time back, so I have just taken the time to check over it again in detail.
I provided the seller with an existing article, taken from a competing website.
The seller rewrote the article as advertised, send me the rewritten document via Google docs, along with a screenshot of copyscape report showing zero matches.
I manually checked to confirm there were no matches according to copyscape.
I also read through the article and it reads very well; you definitely wouldn't know it was a rewrite as its reads like a high quality original article.
I went a little further on this one as well and I selected 3 paragraphs from the original article, read them fully and then read the corresponding paragraphs from the rewritten article.
Reading through, I can see that its been rewritten but there is definitely added value here - the paragraphs have clearly been read, interpreted and then rewritten from scratch (Rather than just replacing words, or spinning the content for example).
The end result is a new take on the content and one that if you read and compare paragraph by paragraph, you can tell that its been rewritten from the source, but you can also see there are additons, changes and additional value in the rewritten peice - it definitely stands up as perfectly decent content in its own right.
I must say that I do agree; the pricing is fairly steep for a content rewriting service. However, I will add that based on what I have seen, it is not your typical rewriting service, there is definitely more value being added here and I would even go so far as to say that the content I received is better than some original content that I have had from other providers at a similar price point.
