Very informational if you're new to the industry but if you've been in it a while, a lot of the content will be review and a few things are very out of date.
2nd to none! I have done a LOT of online learning courses over the years on various topics and trades. 99% of the time you have dry, boring, soulless instructors who think Ben Stein is the epitome of vibrant personalities. Sean's course marries the technical with the practical, woven with humor throughout. Lighthearted and challenging, just the way I like it.
