Has Anyone Used Axton IR Illuminators?

There's not a lot of options for IR illuminators - Bosch, Illuminar, Raytec tend to be the 3 most commonly cited.

One company that is marketing more heavily is Axton. That have a few IR units that are different, a 'zoomable' one and micro one, though on closer inspection we did not find them too promising.

That said, is anyone using them? Does anyone have any good or bad opinions on them relative to better known IR illuminator providers.
