You could say this about most Brands at some stage (even Vu+ and GigaBlue where the air was “blue“ for some time) but they in general learned from past mistakes.
With Octagon and the SF4008, I would freely admit the results didn‘t match promises, but so far the SF8008 delivery has been excellent, with very fast turn around on fixing issues..... so I will test it without any historical hang ups, just like with my Giga4K‘s.
