Nice photos! It looks pretty good inside, and as expected has the HAD1520 ADC chip. I would be interested in hearing your experiences using the scope, and whether they update the features/software.
Enjoy!

I think it has decent hardware.
Pretty hot after + 30 minutes.
You must connect it directly to USB3 port, using hub will not work in my experience.
Can only use a good quality USB cable, the included cable works fine (thick cable), using thinner cable lead to error or excessive noise.
Using included power supply is the best way.
Noise is pretty low. In 2mV/Div, measured below 2mV without test probe attached.
Can not clearly see differences between 8 bit or 14 bit mode, all seem in hi res mode ;D and the difference in sampling rate made it even harder to see the difference. Can not set the sampling rate manually.
No lag in various memory depth in all bit depth mode.
Self calibration runs relatively fast with some relay clicking. Autoset in slow side.
Can not hear relay clicking sounds when changing the coupling mode, maybe use solid state realy?? :-//
The software maybe the weakest point in this scope, very basic functionality, even cannot change background color and wave color |O

Is that P-P or RMS ?
Are you sure it is 2mV? That is not really low noise but very high...
