You're a satisfied customer, and generally the courses are well-received, but some reviewers on Amazon say they're long-winded. Does this match your experience?
From the perspective of someone with coding experience, the pacing can be a little slow; however, that's by design. They're geared for someone just getting started with a language, that's the target market for their courses. Perfect fit for the OP.
Also, there's a button that enables you to speed up or slow down the presentation by 1.5x, 2x, etc. So it's easy to speed through a section if you wish. There will also be challenging sections where you will want to slow down, or review again.
Their "essential training" for a language is a solid, quick, introduction to a language. They walk you through installation, setup, compiling, the hello world program, and a bunch of language fundamentals. For example, in Python, there are two camps: the Python 2, and Python 3. Which one should he learn? At $25/month, I'd highly recommend them; it's a steal.
