Is it possible to share the link to that youtube channel?
You will find a lot if you search with helix gram on youtube. There are lots of it promoting fake helix mixers for instance this one:
https://www.youtube.com/watch?v=MG38CQLUhYQ , and this
https://www.youtube.com/watch?v=zQyWpPqjkGo and so on. Its not from any particularly single channel, there are lots of it. There are so many fake helix mixers out there that one might get confused which one is the real one.
Anyone who is unaware about the helix mixer stopping its service in 2017 will get scammed for sure.
