Honest review:
So after a few weeks of wandering in his group chat i can finally leave a solid review.
The information: 9/10.
The information you get from the seller is basically everything you will need to perform consistent refunds. It includes (But not limited to) your classic EB, FTID, etc methods. Amazon insiders information on how they link multiple refunds, and how do they proceed with it, PR templates which you can edit to your own preferences, updated store lists if you want to hit other misc stores, OFM bypasses and so on. With this information you can make your mentorship cost in literally one refund, or just open a refund service and make your money that way.
The seller: 10/10.
It seems that he's always active lol. Answering even the stupidest questions you could think of. Compared to other refund "Mentorships" where they just sell you an ebook and leave you on "Seen" for days, this is very professional.
The group chat: 7/10.
The group chat is decent, and its active. It's PERFECT to newbies in this refund game, as people share their successes (And fails), so you would know what to do and what to avoid refunding a certain store of yours. But if you are familiar with refunds and how basic social engineering works, you could find the group chat not necessary for your needs.
Conclusion: WORTH IT!
For $450, this is actually a steal. The information you get (Especially the PR templates) will make you WAY more money in a long run compared to hiring a refunder. Almost all the refunders use the same "Tactics" as shown in this mans mentorship, so i really don't see a point of using one nowadays. If you are short on cash but want to play this refund game for long term. Just do a few refunds with a refunder and with the profits, get this mentorship.
