It is a fantastic idea and, with practice, can look effective. Yes, the videos are accurate but
remember they are done by someone with a lot of experience with the cube.
One big holdback - the
video is only that, a video. No words, only video. You would think they could have gotten someone
to narrate the video in English (as well as other languages for those in other countries) who could
add tips on handling, watching angles, etc.
Nice effect, bad instructions.
