As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.
See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

with a different clock it goes up to 6 gig
and it seems as this is a real 2 port and not a 1 plus a half port design

Portable vector and spectral two-port analyzer 1-6200 MHz.
Large touchscreen display and no buttons, except for one - power.
So far, everything I know about this device.
Thank you.
Any infos when they will sell it?

There will be 2 ports.
1 port vector measurement S11, calibrated generator with level control -40 ... 0 dBm
2 port vector measurement S21, calibrated receiver with spectrum analysis function -120 ... + 10 dBm
The planned isolation between ports inside the device is not worse than 60 dB, it may be possible to bring up to 80 dB at frequencies below 3 GHz
I'll try to ask the developer.
Sounds interesting...
Thank you :)
