MY REVIEW:
Originality: 1
The method is very typical, you could probably guess it.
Content: 3
The ebook is horribly written. There's no avoiding the fact. It is ugly and the English is absolutely fragmented. It has pictures, but no effort was put into making them English and terribly placed watermarks and graphics can make it difficult to transcribe. But, it does walk you through everything you need to do to properly get your 'free' V-Bucks. The ebook is not for all platforms like advertised, but because all platforms can be attached to a single EPIC Games account, your V-Bucks will persist.
Method: 3
The method is extremely standard, but still very simple. It is unlikely you will run into problems, let alone ever speak to an actual person. I cannot say with certainty that the OP will even help you if you do.
Price: 2
For the quality of the ebook and difficulty of the method, $20 is very overpriced. However, these are V-Bucks we are talking about... this method could save you some good money if you were planning on buying them anyway.
Overall: 2.5/10
I'll be frank - I had never met a seller as unprofessional as the OP on this website until now. Asking any information whatsoever, especially on making the method work on other platforms, are met with vague responses like "you need to search one on yourself" [sic]. The only support or answers to inquiries you can expect are those that are clarifications of what is already stated in the ebook - the OP has shown zero interest in improving the value by actually discussing how to make the method work more easily across platforms. But, if you have any of the devices needed to perform the SE, you will probably be able to pull it off.
