I have one on order, but I can return it if it's not good.
I see nothing in the group messages or the Wiki.
This is the latest product from SYSJOINT (one of the developers of the NanoVNA-F). There is a Chinese version and an English version and they are not compatible according to the manufacturer.
The Web sites describing the product are:

User manual:
Firmware is not open source and one vendor. ML&S UK, reports they have found some bugs which manufacturer is working on. >>
It connects to the PC with a SYSJOINT Version of NanoVNA Saver. Drivers for WIN 10 are not required. Win7 and WIN8 drivers can be downloaded from SYSJOINT.
Looks like it is well built but S11 and S21 dynamic range is something to take a look at.
