Alan Ross wrote a review of this head recently. I too had thought it would be better than sliced bread. He didn't sound as if he thought it was quite so wonderful. And at the price, to fit an enlarger for which one cannot get pieces and is too bloody large anyway, I decided to forget the whole thing. After all an enlarger is just a simple projector and doesn't need to be so fancy. A little light leaking can be dealt with easily. And if it can be aligned, one is about as good as another, as they say, in my opinionated judgement!
