I bought one a few months ago for $529 and am very pleased with it. You'll see the discount next 3 days upon checkout.
Compared to the Xiaomi 144Hz monitor, it has same brightness, better curve (1000R Vs 1500R), HDR support, and 2 speakers.
It lacks one HDMI port.
The OD:7ms response time seems to be slow but Kogan traditionally uses the slowest GtG time in their spec compared to other manufacturers who uses average GtG time, so this 7ms response time is not necessarily worse than others.
My own view as a use: a decent display. The HDR and speakers are just there, close to useless, but the 1000R curve is nice. Build quality is much better than average.
Factory colour calibration is way too warm. But with a proper calibration profile it's beautiful.
The control style is like samsung's, one stick from behind the screen does everything.
And it has RGB!!! (Can be turned off)
I'm sharing my colour calibration profile for this display, for those who bought it and want to try my taste of colour:

It works on both windows and mac.
For those who use mac, you will need RDM tool to use native scaled UI on any WQHD monitors, otherwise you are stuck with tiny text and menus.
I have achieved great results with that tool.
