The first time I used these was May, 2017 in Cadillac, MI at a manufacturing plant. It went very well!  They're entertaining - funny, even - & were very well-received by the attendees.  A month later I was taking a TIG class at Lincoln Electric in Cleveland, OH and mentioned to the instructors that I'd started using their videos in my training programs. They were happy to hear it, but a bit sheepish at the same time, saying, "you don't think they're a bit too silly?"  I responded, "No... well yeah, they are pretty silly, but they check every box, & in an entertaining way.  After all, it's my job to train people to work safely, & these videos not only keep folks awake, they make them laugh!"
