There are a few useful things in his videos but not as many. I was watching his Youtube channel for a while but found he didn't deliver on his promises. He'd tell us how he was about to show us how to do [insert some topic here] but after all the words were spoken and video shown, you discover he hasn't actually addressed the topic in any meaningful way. I also communicated with him a few times and he was never able to answer any of my questions, often just repeating back what I had just said and then telling me I'd need to bring the car to him for diagnosis, even though he knew I'm in Australia. Also, watching some of the mechanical work he and his team have done to be pretty rough and unprofessional.
