Excellent training. Very detailed with excellent filming to give hands on experience. I couldn't be more pleased with the set of 4 DVDs. John knows how to get down to the details that are required to properly repair clocks. He also passes on many of those important items learned through experience that are not in the books.
Excellent. So very professional with extremely clear visuals and verbal explanations. Like working beside John as he goes through his teaching. This comment applies to video 1 and 2 also.
