I'm very impressed with this vector network analyzer. I'm using the NanoVNA-F to analyze the SWR of my ham radio antennas, which span from 1.8 MHz to 450 MHz. The 4.3" screen is easy to view and large enough that I can select options on the touchscreen with my index finger. Because it's portable (7 hours expected run time on 5 Ah rechargeable battery), I can take it up on the roof to fine tune a nine band vertical, or measure SWR in the convenience of the ham shack. Accuracy is outstanding and definitely better than the radio's built-in SWR meter. While using the VNA in the ham shack, I typically run PC software (NanoVNA Saver) to graph each band's SWR, which I can then save or print. The number of data points can also be increased using NanoVNA Saver. Do a Google search of NanoVNA PC software to find the file downloads. The user manual can also be downloaded, as well as firmware update information.
UPDATE: The user manual for the NanoVNA-F can be dowloaded at deepelec dot com under the support page. The current filename is NanoVNA-F_Handheld_Vector_Network_Analyzer_Incomplete_Manual_v1.0.pdf. Despite the name, it looks fairly complete and includes firmware update instructions. I updated the firmware version from 0.0.4 to 0.0.5, which extended the frequency range up to 1.5 GHz. Firmware updating is very easy and can be done without removing the case. I'd suggest waiting a few days after new releases are announced before downloading and installing them, to allow time for new bugs to be resolved. The 0.1.1 release just came out a few days ago, which adds a TDR and improved marker functions. It's nice to see the frequent updates which add features and improve performance.

A great product! Very nice and neat case, small size, is very accurate in its measurements (I have multiple calibrated meters and this one is just as accurate) and has all the functions you need from a multimeter plus the large screen ability makes it very versatile.
Both my colleagues saw me using a multimeter, consulted me about it, they both bought one, and each was very happy with his choice. I recommend it unreservedly.

Awesome!
In this pic a cellular antenna is being tested for LTE band 2 in the 1.9ghz range. You can clearly see the 3 responses from the antenna at 1908mhz (AT&T and TMobile phone transmission), 1943 mhz (AT&T phone reception) and 1970 (TMobile phone reception). So cool! Worth the money.
