from what i see from youtube on their previous project + the price, i guess quality is so so. just my guess.
if u want, i can intro you my reno guy who did everything for me, one stop center. workmen is i can say very good

Doesn't he work with them? Or worked with them in the past?

I think in marketing or something like that.

I wouldn't speculate on this lol

As I don't see any constant active branding of TMoG in his channel

That said, I definitely can see that he is somewhat close to them be it in work or personal accords
