Specs-wise its looks like an FNIRSI 2C53P in the shell of an 2C23T! Very nice indeed!
Is there someone here who have bought one yet?
Not available at the moment on aliexpress, but 7 sold.

On the 2C53P
Storage Depth is up to 64kB
Generator Freq up to 10MHz sine and 5MHz on the rest of the waveforms
Probably the same spec on 2C53T

Good day. I apologize in advance - I do not speak English (communication through a translator), so there may be misunderstandings. I am the owner of this device (2c53t). I also have 2c23t and ZOYI ZT-703S. Therefore, I can compare them.

In general, the problems of the 23rd were partially removed, partially left, and new ones were added. The problem of increasing the set signal remained (when measuring the oscillogram, pressing pause, then changing the time does not lead to a change in the diagram on the screen.). This remained.

The problem of triggering on single signals is more likely solved than not. The front is not always in the center of the screen, but I did not notice any non-triggering during observations.

but the generator will cause problems now. If at a voltage of 0.1V the 53rd shows itself better than the 23rd, then later everything is the other way around. I think everything is visible in the photo. Yes, now the maximum frequency on the sine wave is 50 kHz. They added new signal forms, but why are forms of such quality needed?

Lissajous and mathematics are of course interesting, but... but at least they work, unlike FFT. I couldn't understand the spectrum... Maybe I haven't figured out the device yet.

It is very interesting, has the release of 2C53T been canceled? Somehow there is no new information or reviews about him...
