Negative Positive
Title: Poor content, just not worth the money
Review: This e-doc has 32 pages of which 12 are acknowledgements, ads for other docs and so on. The remaining 20 pages seem to be displayed randomly by Acrobat Reader, as the case of some "internal errors" may be... But you can get such (poor) content from elsewhere on the internet for free. Moreover, it is just a scanned book, so you will not be able to copy text into MS Word. Do not buy the same lemon I got, for refunds on digital items are not easy to get.
Is the review positive or negative?
