I made it 1:20 into this and got no information I didn't have from the intro text. I can't bear to endure 20 min. of it.
Like most videos (and, all too sadly, most documentaries), this thing has a SNR (signal-to-noise ratio) of about 0.05, max. I am not interested in hearing these people chat with one another and watching them shove the product around on a table. Furthermore, ~all~ videos, even those packed with info, run at their own RIGID rate, which is absolutely guaranteed to be sub-optimal for ~most~ viewers: all people are different, and their cognition runs at widely varying rates. Because of this, videos are the very worst way to convey information.
If you have a file to ~read~ that gives all pertinent info and shows sample pages (reduced in size if you're afraid someone will steal one), please put a link to it above the video screen. I want to know what I'm buying before ordering.
The price is right but the sales pitch is rotten. Maybe you can use it for mulch.
