Cheap nano Vna's

[dr pepper]

They are all over ebay for 30 notes, 50 bucks or so.
So I got one after watching some youtube vids.
I have to say they are pretty good, though the display is so small I need glasses, but it also works with a laptop/pc.
It uses a Si5351 dds chip, so the fundamental max freq is 300mhz, but the software uses harmonics to go to 900mhz, measurements are a little more noisy but still useable, and unlike other cheapies the nano has 2 connectors and can measure gain/attenuation, as well as return loss.
Anyone else got one of these gizmo's, what do you think.

For the cost of a take out you can have one.

You obviously have more expensive takeouts than I do!
