Great class, covered all the major points, and thoroughly explained how the system works. Lots of good tips on how to efficiently diag and be more profitable in the shop.

Everyone really enjoyed the class and thought it was very well done and everyone loved the trainer. He did our last in-person class and he is very sharp and communicates very well. Great material and the feedback I've gotten and the bits that I dropped in and watched was impressive. Y'all did a great job.

Well planned and executed. Would also be great to see actual slides or pictures of amp clamps testing the circuit that's being diagnosed. Kris is very knowledgeable and helps me to find shorter ways to get the best result.
