It works as expected, very useful tool
I was a little sceptical about this device but it has exceeded all expectations, a little tricky to navigate the menu structure (use the supplied cheat sheet and it's a breeze), otherwise it's a great tool with an easy to read display.The only critical comment I can make is about the charging cable, it's a very cheap usb-c cable and doesn't work one way round, I use a higher quality cable and have no problems with it.

Absolutely Brilliant!!
I can say is this piece of equipment is worth its weight in gold, I love experimenting with antennas and this allows me to do that, I’m only using one facet of this great piece of kit and it has proved invaluable already!!Plenty of user videos on YouTube. I highly recommend the product, great value for the price, clear display screen. Really glad I went for the H4 version.If your into ham radio or even helium mining and think your antennas tuned, use this device and it will give you an accurate reading, I never rely on the manufacturers spec and always test.

VNA
THis VNA seems to work well. I have mostly used it to measure home made Common Mode Chokes and to check VSWR for my vertical HV antenna. It seems to agree with my MFJ -259C.

Works But!!
Well I would have given it 5 stars but it didn’t work out of the box. After many tries I found out that removing the 4 screws holding the case together it would work perfectly. I’m guessing that the top case was making the tft screen thinking it was being touched.Having had this now for a few months. I would say it’s totally useless if you want it to work for more than just a few minutes. Very much simpler to use my array of other test equipment. Far too many issues with this one….
