I ordered that one too, thinking that I'd have a better shopping experience w amazon if something went wrong. Nothing did. Nice product. Good quality unit as far as I can see, 50 ohm load is right on (Fluke 87). Battery uses plug, not solder. Shielded, very clean construction techniques...not sloppy at all.

Has operated well, upgraded firmware. Runs nanoSaver on Windows 10.
I asked vendor a question; got prompt, brief, clear reply.

However, the unit came w only 1 ea short, open, load, and I think that it really needs 2 sets to do a complete cal. I'm new to VNAs, so still checking this out.
