What I don't get is why people keep calling it controversial or defying the laws of physics.
Because (assuming the experiment is correct) the force the EM drive is producing is more than 3 orders of magnitude greater than a photon drive.
They're claiming 0.4 newtons per kilowatt.
That's about 9 times the thrust of an Ion drive, without the propellant.
It could be a hoax, but if so, it's a damn good one.
