I received my order yesterday and have had a chance to look at it.
The output from the samples I have taken is very good. Not saying that there are not some 'awkward' phrases and words but none have been horrible.
I am happy to use this document for any backlinking involving this niche, or related ones.
Two things I'd suggest though:
1) In future offerings can you vary the information load a little, perhaps even by varying the number of paragraphs but better yet by having paras with different content in them.
Doing this would enable greater use of the same document higher up the pyramid closer to money pages. (indeed multiple use on tier one sites - the grammar and syntax seem up to the job!)
2) Can you provide an email bounceback or a redirect to an info page after ordering telling users that delivery is manual. Or better yet automate the delivery?
Anyway, next one of these that you come up with I will buy.
Two thumbs up!
