I've just completed viewing the 260+ (at this time) individual tutorials offered here. I knew very little about PLCs before starting, but having reached this point, I feel I have a very good basic PLC foundation to reference in all my engineering, manufacturing and automation circles. I feel it was a very affordable education given the low cost subscription and self-paced learning. The tutorials are well produced, and pretty thoroughly explained by a well-spoken narrator, who seems to prove that he knows what he's talking about as well.
I did not have Siemens PLC software to use for hands-on exercises, testing or proving, but I still found that I gained valuable knowledge. I do suggest to any readers of this post to have the software and/or hardware available for your own use if possible, as it will definitely make the experience that much more useful.
On a constructive criticism note, and not everyone will find this to be a problem, I would ask that the narrator of these tutorials PLEASE reduce the repetition of transitional words between statements, especially the word "NOW"! I understand these transitions are used to set the listener/learner up to pay attention to what is being said, but silent pauses work just as well, especially if voice inflection is used properly. I simply found the egregious use of the word "now" and "as you can see" more and more distracting as I went along. When "now" is said 20+ times in a 6-7 minute video, it just distracted me from the tutorial. I began to predict when the word would be said over and over again, and it diminished the otherwise high quality of the tutorials. So, again, it may not distract others, but it definitely had that effect on me. I believe the overall quality and effectiveness of future tutorials would be improved for the listener if this approach was revised. Thank you.
