    This time the Nano VNA is working. The box was a bit smashed from on edge but no damage inside. Very handy very useful item. Worth for the price no doubt.

    Very nice and precise analyzer. All needed parts inkluded in the box. Recommended :-)

    Nano vna works well. One of the sma cable is short.

    Shipping is super fast as usual. Packaging is OK, but plastic could not protect the paper box (which is nice, but not very practical). As I have an older NanoVNA-F I can compare H4 with it. H4: Electrically it's better without hesitation. It has no trouble to keep everything below -60dB till 900MHz, and -50dB till almost 1.5GHz. This is really impressive. It's lighter due to plastic case (I regard this as a positive thing). LCD size is a bit smaller than F, but as there is no scale it looks almost the same. LCD visibility (especially from SMA side) is slightly worse than F. Touch reliability is slightly worse than F. Pushable rotating knob is still nothing to write home about but it seems to work. So far I could not locate a new SW version (I mean binary as I'm not keen compiling it myself). In addition the menu cheat sheet contains a DFU menu that is not found on the actual menu of the SW... So it's unclear to me how firmware update supposed to be done if it's necessary. In overall it's light and electrically so far the best package (it's a very good value). I look forward seeing the V2 variant with a similar size display.

    Great little device, very useful for my antenna designs testing, as well as many other projects, easy to read screen indoors, outdoors it is near impossible to see the display, I set the brightness fairly high to see it better but this eats the battery faster. Also, I found a major issue with connecting to a PC & a Mobile Phone, the issue being that it will not connect to either, despite days & days of searching for possible solutions, it appear that it all comes down to the DFU driver, which if you are one of the unlucky ones to have Windows 10 with driver issues then you will not be able to get it working. WORSE STILL, there does not appear to be any third party drivers to use instead. I purchased a genuine OTG adaptor for connecting to my mobile phone, but this also fails to recognise the device connected. so, maybe an issue with the unit itself. It works for what I need it for so I will make do for now. Otherwise a very nice addition to anyone's electronics toy box.

    Interesting device. You have to keep in mind when you work. That it is designed more for passive chains. The circuit under investigation is supplied with a rather large voltage, the meander is a rectangular signal with an amplitude of about 0.7 volts. That's something to consider if you're researching amplifiers. As a spectrum analyzer, the bandwidth is quite wide and has two maximums. As a signal generator - also gives out a rectangle and the amplitude is not regulated Do not interfere with the external аттенюатор. Easy to use in the field (not in bright light), for on-site repairs

    I haven't checked the operation in detail yet, but it started properly. I was surprised that the box in the package is so good and solid. There is no shortage of contents. It was not wrapped in cushions, but it seemed that they handled the transportation along the way. (It was placed in the bag of ANA CROUP's air carrier, where the starting point was GAN and the destination was TYO.) I'll try to make use of various things from now on.

    Product as described. Good visibility on the 4" screen. It came with an older version of the firmware but was easy to update to the latest released version.
