Very flimsy videoquality, music too dominant (marching music ??) Did Xi Jinping choose that 😂, barely readible subtitles, Never saw such a bad video, congrats with that !
Total crap for audio. Can't watch. Audio is needed to listen to grinding process for hallmarks of chatter and edge engagement but this.... The shyte "music" overlay at distortion wrending volume, the background cacophony, and the operator thinking that talking over the process is necessary to teach. NO. this is pure supervisory failure. The supervisors that insisted the operator talk over the process are what kill this for it is patently obvious that they drove the rest of these atrocious production value choices. Use diagrams and subtitles BEFORE or AFTER to setup and explain details. This is a vitally important arcane tool crib skill set are these clowns are blowing it with the worst audio in history. Again, the audio of tool meeting stone are the ONLY thing we should be listening to. Not a single human voice should be heard as well ad the background chaos. Pull this atrocious thing down and do it over.
I suggest that if you want to sell tools to US customers, you do more professional videos. Use english in a quiet environment, get rid of subtitles that can't be easily read. You need some US production quality here. This is from someone who wants to buy.
Have had consistently good results when buy stuff you folks, in the rare case of an issue or problem with a product it’s always been resolved very quickly and conveniently. Two Thumbs Up
