For people who may have Kogan First for free from their Kogan Black credit card or similar arrangement. Don't bother if you don't. It's a bad deal at $1200.
IPS panel, so good viewing angles at the cost of average contrast (standard 1000:1, may have some IPS glow).
2300R curve, which is on the subtler side. Some who sit close and want a stronger curve may find it too weak.
USB C supports display and charging at the same time (has to be a proper Thunderbolt USB C cable, not any USB charging cable that came with a phone) at 65 watts. Should be enough to slowly charge most laptops, as long as they are not at 100% load all the time.
Resolution is 3840 x 1600 and aspect ratio is 24:10. If you want to play games, this is effectively between 1440p and 4k at 16:9 (~74% of 4k at 16:9). So it may lock you into buying expensive top end GPUs, partially nullifying the $500 price point.
PPI is the same as a 1440p 34/35 inch ultrawide (around 110), but physical size is wider and taller by a few cm.
If you have a 27 inch 16:9 monitor, this is around 1.5 times the width (minus the bezel between the real monitor and imaginary half monitor) and a few extra cm in height.
If you're planning to game on this, make sure to check how your favourite games handle ultrawide resolutions. Some competitive games are even actively hostile to ultrawide and will insist on a 16:9 viewport as standard.

If you decide to try using this with a Mac, it may be worth trying BetterDisplay to unlock more options for UI scaling.

Free version should be more than adequate for most people.
If you're wondering why this is so cheap, it is likely these are B panels from LG's 38 inch ultrawides (the specs are suspiciously similar).

If you don't know what B panels are, these are essentially panels that are functional, but don't pass high enough standards for LG to sell under their own name, so they get sold unbranded for others to stamp their logo on, like Kogan. Maybe the factory colours are a bit off, maximum brightness slightly lower, etc. Should be fully functional, not an excuse for them to not work. Better than throwing them into landfill.
Last of all, if you are feeling FOMO, this monitor has gone on sale for $500 every few months for Kogan First members, so there's no shame in waiting for next time.
love the op's details!
