Anyone use Sporty's new CFI Prep?

Looking to see if there are any reviews for Sporty's CFI prep.

Seems like one of the few courses out there that preps you for both the written tests AND the oral exam. I'm excited for that because I've been dragging my feet in getting my CFI for years in fear of not being prepared for the oral.

Any other suggestions for comprehensive prep courses would be great!

Thanks folks!
