Most of those reviews are done in the US against US radars. Here the main threat is laser and Multanova. You need to find a review on those.
For multanovas I did one here:

And for laser this is the best test I've seen:

Dash mounted K-band is easy to detect with any reasonable detector.
Also Craig Peterson of radartest.com consults to Beltronics. It is worthwhile having a good read through:

It's a big (long) read but worth noting. Craig Peterson (radartest.com) has been testing radars for many years, you could call him the grandfather of radar detector testings, but there seems to be a few issues of late...you may also like to read this:

I am more than happy to lend you an Escort for a week and then a Valentine One, so you can compare. I ran a Bel 990i for 3 and a bit years, then a RX65 for nearly a year, and then an Escort for almost a year before I finally tried a Valentine.
If budget comes into it, then the Escort is my first choice. It's a top detector, and has never let me down. It has always given sufficient warning on Multanovas. But if I could afford it, I'd choose the V1 any day.
