as what seems to be the issue with the rest of their videos, the information provided is better than not having any or what's disseminated by some bozos on the internet. BUT in the end, there are some minor bits and pieces that could (should?) be changed. . .
For example, there are times when stroking twice is needed, but it should be an exception. Showing a video with stroking twice creates an impression that it is the right way to do it. Similarly, there are hot peel and cold peel transfers depending on the ink and paper. Saying plastisol transfers are hot peel is incorrect. Also, the 12 seconds might be right for that particular combination of ink and paper, but that too can vary. Add in not preheating the paper and a production method that will generate 15 sheets an hour and I'd grade this video at C-.

p.s. adding a link to a location where most of this is explained would make a huge difference. Even a link to somebody else's material. . .
