Arstechnica is critical-

Another problem that occurs in these experiments comes from
determining when the pulse actually arrived. If you analyze a pulse of
light, you find that it is made up of a huge number of frequencies
that, as you move away from the fundamental frequency, get lower and
lower in amplitude. Once you look at the experimental set up in
detail, you find that it is triggering on the pre-pulse noise
generated by these high frequency components.

Aephraim Steinberg, a quantum optics expert at the University of
Toronto, Canada, doesn't dispute Nimtz and Stahlhofen's results.
However, Einstein can rest easy, he says. The photons don't violate
relativity: it's just a question of interpretation.
