I got a vouch copy about this product from the OP and this is my honest review.
The method works and is very real with full support from the company itself, i also feel that the op can as well give this out for free or charge a lower amount on it because it is really too simple a method but that is left for her to decide.
I did not include vcc because i do not need the dns at present but i will certainly do that later and this is to avoid it running while unused since 12 month is 12 month.
Good product, i vouch for it.
