I really don't see it myself when there isn't even a video showing the machine working. Some people will just buy blind but a lot of people want to see how it performs before parting with their money. The same applies to Nokta Makro, I don't want to hear it - I want to see it.
Depends who does the videos. I trust Gary, but in many other cases, what you see isn't what you get.
Many early videos will be attention seekers and people wanting to increase their channel subs, and in my experience much of the early feedback will be unreliable, and that's putting it politely. if you want to know what a machine is like, I honestly believe you have to wait a good few months for a lot of feedback and then carefully sift out the facts from the fiction.
