This is very cheap pricing. Not sure about quality.

I see these on ebay, even the 75 inch version and do wonder what they're like in person.
These will be on the same level as Kogan (Sh1t) 1200:1 contrast ratio is a big issue, after shipping and manufacturer mark up there's very little left over for actual materials and technology/R&D.
Would personally stick to a TCL or HIsense as a bear minimum.
But hey dollar per inch basis you can't really go past these ;)
