When dealing in products from China, whereby some unscrupulous few can produce life like looking eggs from cardboard and passing off white powder as baby infant milk powder, one best be cautious, more so with the current rage of AI video creating programs that can produce absolute realism in 4K standards, with voice, music, backgrounds, etc.....
The insignificant nobody me is NOT saying that all products from China are bad. No. There are still some manufacturers whom are scrupulously honest, to earn an honest living to feed their families and loved ones....and would need time and support to build up their branding and legacy...
Just be cautious, and if one see some extraordinary product on social media, best wait awhile for a LIVE demo of the product in front of you, not on video as with current AI tech, even realistic cheering crowds and voice overs can be created.
