Disclaimer: I received a free review copy and have gone through the entire course, some videos multiple times
This course is pretty unique in the sense that it's shorter than many courses, but that is because it doesn't spend time on the basics of FB ads. It sticks very strictly to the point. OP mentioned this in the thread, and I will second it - you need to know the basics of FB ads + maybe some small practical experience to make use of this material.
If it's rare information you're looking for, the course offers some information that I've honestly not seen for free on Youtube. I've watched maybe 20 FB ad tutorials/guides over the past 2-3 years, and a lot of what Slava says are things those content creators didn't want to give out for free, or for cheap either. I liked that the whole time on the screen he is explaining things using his own campaigns as examples, no made up crap. He shows samples in niches he worked in, ad creatives, and everything like you're standing over his shoulder.
A lot of the course is about explaining what NOT to do, which I think is also great. I think if an averagely capable person followed the practices outlined in the course they would likely save more ad budget money than they had spent on the course itself.
Is it worth it? I'd say it is, if you want to be truly good at ads and match professionals. Getting to talk to Slava is a big bonus too, he is very honest and upfront with you. That's my review, good luck with sales.
