Econplusdal books

I'm in Y12 doing Econ and I just wanted to know how good Econplusdal's analysis and evaluation books are, if they've got any different/ additional content to his videos and are thus any more useful than his videos?
Thanks

I spent £90 on them in i’m in y13 i find it quite useful as i can find proper evaluation in one place usually my other econ revision material dont contain in depth evaluation but i don’t think its worth £90.

i have the book and not gonna lie it has saved me, I went from Ds to As by purely understanding it. It also adds extensive details on each topic and is a rather long book, I hardly use any other resource to revise and i feel ready for my a levels in May.

in terms of the actual content of the books, is it the same stuff that he covers in the relevant videos or has he added extra detail to the books? TIA
