It looks like it was ripped from a VHS tape, so if you're the vintage type, you'll appreciate it.
But, seriously, this formality doesn't really matter. It's very well done. The basics are
scrupulously respected : the explanations are clear, the camera is always in the right place, the
slow motion is very helpful.Finally, read the summary: you will understand that the tape can keep
you busy for a loooong time. If, like me, you are an involved hobbyist, the price is well worth it.
No doubt.
