Sorry for the delay as it has been a long day for me. I have read the guide and it does make sense and probably works quite well. The guide is short and to the point which is nice, and it is well written. While I can not guarantee that this will work 100% OP is not trying to scam anyone here. For the price, this seems pretty legit to me.
*Disclaimer*
I am not saying buy this guide, but this is definitely not a scam. I have not tried the method, but it is pretty easy to tell it would work.
