Great tool

Unfortunately, the only "instructions" included are in the form of a table which is not easily followed. Fortunately, YouTube has quite a few videos explaining how to use some of the functions, at least the ones I need. Item is good quality but it is getting docked 1 star for the lack of adequate directions.

It's worth the price (money... and time to learn).I've used it to get VSWR (as a function of frequency) and to find impedance mismatches of components (including poor SWR meters and switches), but I have only used a small portion of its capabilities.Lots of helpful stuff on YouTube.

The lack of documentation is a horrible thing. I paid for a SID card as a bundle. I couldn’t even see it initially. The one page chart of directions for use are pathetically inadequate.

I have used this on several antennas and am glad that I got it.I got two antennas were bad right of the box and this tool probably saved my radio because they were dead shorted from the factory.

You should buy this nanoVNA. The larger screen is awesome. There is no other piece of equipment that can be beat for the price.This is an awesome tool. I wouldn’t go to the moon with it— but it will exceed your expectations as a hobbyist on Earth.The supplied dummy load in the calibration kit read 50.7 ohms on my Fluke. A little higher than I’d like to see, but it’s close enough for my uses. TIP: If you use the NanoVNA Saver software, you can input your actual dummy resistance during calibration. The software (not included but available online for free) really opens up what this thing can do.I bought a NanoVNA months ago, but everything about it was awful, I returned it. I couldn’t get it to work properly and the touch screen calibration was off by a mile. The one I received from the seller TOSTOG is awesome. It works perfectly. I had it working in minutes and it’s provided hours of entertainment for me with testing various ham radio equipment. SWR on my antennas? Check. dB insertion loss of my antenna switch. Check. Insertion loss of various connectors? Check. dB loss of coax cable at any conceivable radio frequency? Check. Measure reactance? Check. Make a smith chart of my antennas? Check.Did the NanoVNA match SWR readings like my Rig Expert? Almost identical. Within .05 VSWR, then important part is resonance was shown at the same frequency. Did my coax loss readings at multiple frequencies match manufacturer specifications? Almost identical. Within .07 dB. I attribute some of the error on db loss for manufacturers do not include coax connector loss on their spec sheets, it’s for the coax only. I even got the idea to test the loss of some no-name brand coax I have laying.Be sure to grab an assortment of SMA adapters if you don’t already have them. You’ll want an assortment.

With the Youtube videos (which you must watch) the Nano is easy to use and accurate. It has way too many features for me to use. I gave the Easy To Use a 4 because the supplied documentation (and wierd flow chart) was quite inadequate.
