The information is certainly top notch. The presentation leaves a bit to be desired (IMO). Some of the narration has issues that I find almost unacceptable in a prepared format. In a live class I don't mind throat clearing, stumbling on words, long pauses, etc. But in a format where you can rehearse and do retakes it is less acceptable.
But I'm one that demands excellence in technology driven applications
Ah I like the less than formal delivery - appreciate that it is a human giving the course and not some polished commercial product. But the glitchs do bother me to.
