Great product, really detailed and easy to access information on everything you need to know as a CFI.
I've been very impressed with the syllabus, checklist and lesson plans so far. I've used materials from ASF in the past but they are dated - I like the idea of continuous updates and the ability to provide feedback.
Well worth the low cost for everything you get. Along with free updates. As a CFI, new or seasoned, this is a great item to place and review in your toolbox of training tools.
