Hi Deb, I looked into them and thought they were value, but it turned out they weren't. They spin a yarn that somehow when they print a code on your product that it'll protect your copyright. It won't! People can copy your content, mask the code and there's no Book Funnel police out there that even cares. It amazes me that there's 'authors' and 'people who prey on authors'! Wanting to charge for mentorship, add ons you can't do without, in a world where 95% of authors don't even cover costs. I get 2 or 3 gmail account scammers every day trying to flog me some magical way of becoming successful.
