Gosh, groundless insinuations - how grown up.
Manufacturers try really hard to find out the outcome of reviews before they're published, but it's a total no-go - the first they get to know of the star ratings are when they read them in the mag, same as the rest of you.
Some will claim they knew (dealers, for some reason, often trot out this tired lie), but they don't. And neither do our commercial team.
Also, of course, unlike some rival magazines, we don't involve manufacturers to get involved with our tests as reviewers. They get to hear/see their review kit working if they wish (to avoid those damaged-in-transit situations, which can happen), but then we kick them out before we get down to comparative testing.
