Very much still around.  Hmm.

It seems the team is actively updating the demo videos, on both BiliBili (42 videos this year so far) and YouTube (12 videos this year).

They need to update their web site so you can figure out what they sell without visiting a dozen, seriously slow web pages.  They have a sort of selection guide, but it doesn't include many of their models. 

This is what happens when engineers try to run a company.  No, if the engineers were running the company, the web site would be blindingly fast. 

This is what happens when Ferengis try to run a company.

I risked and got one. Now I regret it a bit because the software can be confusing and sometimes counterintuitive:
https://www.eevblog.com/forum/beginners/pausing-and-inspecting-signals-on-usb-oscilloscopes/

Essentially, after you have captured a signal using a trigger, it feels like a teaser - the program clearly shows small thumbnails of something they have named PC cache with your signal barely recognizable there. Still, you just cannot click/zoom/navigate/whatever to access any of those captured frames in their full glory. There seems to be something tricky to access them, I'll ask their support about it.

I'm glad I didn't buy a more expensive model because that also would have the same software issues. I also experienced a few plot crashes - got a big red cross in the plot while everything else worked, and sometimes it gets stuck in the wrong voltage range showing 20V instead of 5V (switching divisions back & forth fixes the problem); and sometimes it shows I'm in preview mode while I'm actually in live mode. And also recording navigation is inconvenient, no way to pause or scrub the timeline forward/back to find the signal (but not sure if other scope software has this feature?).

Wow!  That sucks... 

I bought a Hantek scope once, for ~$80 I think.   I never got the software to even run!  I contacted the seller after finding no way to contact Hantek with a useful response.  They wrote back that they could not find where it had been delivered, seems the UPS ticket was corrupted or something.  So I got a full refund and the box went in the back of some drawer. 

I had a chance to dig into the design later on after others did a tear down and it pretty much was a piece of junk.  It had a logic analyzer and scope combo, but they weren't in any way a "combo" other than being in the same box.  They had entirely separate interfaces and no cross correlation. 

I'm glad I got my money back without a hassle and even saving me the frustration of finding out how unuseful it was.

I would not say that this is unexpected. I have never seen a PC scope UI that did not suck. They are clearly implemented by programmers that don't actually use those tools. And apparently they are not acting on the user feedback.

The UI in the linked topic is a perfect example. Rotating knobs like this are a perfect example. If you see a PC scope UI with rotating knobs, you can rest assured it will suck.

I actually quite like the software that comes with the Digilent Analog Discovery (Waveforms). And the PicoScope 7 preview I think has potential but still needs a lot of work.

But unfortunately that is the exception and not the rule. If you are going to buy a PC based instrument, it is always a good idea to try the software first, there is often a demo mode. If that is not possible, maybe look elsewhere.
