NanoVNA-H4 vector network analyser reviews

I bought from eleshop as a result of the recommendation on the nanovna.com page.
The delivery was fast, without problems and the product corresponds to the expectations for this price level. I have only one complaint, since most DUT have SMA female connectors and the calibration reference plane must be as close as possible to the DUT, we should be able to do the calibration at the end of the measuring cables. For this we need the SMA female calibration kit, the one supplied with the device is mostly useless.
