NanoVNA are they any Good?

Leon Huang, BH5HNU, of DeepElec just told me how to make the NanoVNA-F read in the R+jX Ohms format:

1) Start at Home Page
2) Select MARKER
3) Select SMITH VALUE
4) Select R+Xj (R+jX)

I only use this function at one frequency, f, at a time, so I do the following:

1) Start at Home Page
2) Select STIMULUS
3) Select CW FREQ
4) Enter frequency, f, on screen keypad (3.885 MHz, for example)

The screen will now show S11 SMITH 1.0 R+Xj format. I couldn't figure this out on my own.
