This is a product sample send to my Blog for free, so to be reviewed.
I am having direct PR with the company in Taiwan and with many others.

My estimation is that it availability internationally will start in three-four months.
According to my first informations it pricing should be close to 150$ USD or less.

Multimeters including L, C, R, + a zillion other functions have been around for more than 2 decades, as far as I know (could be earlier though).

I do not think so.
But if you have buy any, and tested it, then feel free to post pictures and comments about it.
You link is misleading, pointing to a web page with a product with fake specifications.
Do you own this website ?

I do not own any website, or have any commercial interest whatsoever.

The product I linked was just the first example among many others.
Here are a few more:

AX-588B digital multimeters with inductance measurement, AX-588, AX-588B |EN|

Wintex DT2200 Digital Multimeter

This one even includes a pyrometer:
Multimeter Thermometer with Infrared

So far, I didn't manage to find one that includes a blood sugar meter, an altimeter and a kitchen scale in the same instrument, but that's probably because I didn't search hard enough.

Now, what is the actual worth of these functions? from experience, I imagine they could be quite accurate for simple cases, like standard chokes or Xover coils, but I wouldn't trust them for difficult cases, like measuring the magnetizing inductance of a 50Hz transformer, or its leakage inductance, or the self-inductance of a WW resistor

Mastech MS8269 Digital MultiMeter Piece of crap meter plus not true LCR function. LCR do a lot more than just give an arbitrary value at an unknown frequency. They give you a variety of parameters (theta, D, Rs, Rp, Cs, Cp, etc.) at very precise specific frequencies. Allowing you to evalutate the performance characteristics much more accurately.
AX-588B Not sure of the quality of meter, though it looks like rebadged Vichy crap like the Sinometer below. LCR function is not true LCR function (see the Mastech)
TPI 192 Meter Decent meter but not true LCR function (see the Mastech)
Sinometer VC9808+ Rebadged Vichy crap, same thing about the LCR function (see Mastech above)
Wintex DT2200 Digital Multimeter Not sure about this one, it looks deent but the details are sparse at best but it doesn't appear to have true LCR function. Jury is out though until I can find more info.

This one even includes a pyrometer:
Multimeter Thermometer with Infrared That is a truly WEIRD beast of a meter. I'm not even sure what to make of it. It doesn't have true LCR function (see Mastech above)

So to sum it up, you found a bunch of meters that can measure inductance but do NOT perform LCR functions like a true LCR instrument. The meter Kiriakos is linking to has a FULL LCR setup built in, it measures a variety of parameters at specific frequencies just like a real LCR. WHile less capable than the DE-5000 it's much more capable than the toy LCR functions you linked to.

Honestly, I think this is a pretty interesting device. If they could hit the $120 point, I think this would be the go-to recommended meter for a LOT of hobbyists. Der EE is known for making good stuff, though usually they miss the price point by a wide margin on their meters.
