Looks good on paper ... but  Time owned: 0 to 3 months
I ordered this kit and the USB interface for it and it was shipped out immediately. I received it in Canada about a week later.

You can build the kit in a few moments (you need 2 parts, the USB Interface and the actual SWR meter).

The USB Interface and software work fine, but sadly the SWR meter is pretty much non-functional. It measures bad power readings with no RF input to the unit which is unfortunate.

Several emails to the company have gone un-answered and there is no telephone number to reach out to them directly.

It is likely a good kit if you want to use the AD8307 and expand it so it actually functions, but if you expect it to work out of the box you may be disappointed.

I am a very experienced builder and so I am pretty confident that the failures are not due to my construction techniques.

Your mileage may very.
