I was tempted too, but since they charge raw prices per part, with the fewest possible sprues, leading to a choice of models very reduced (in only one or two parts), and none so far is ready to be printed.
I saw too that they remove the struts and I have mixed feelings about that.
They have also issues with this material (see their material forum) and the price is not set.
If the resolution is the same or the like than Form2 or Ember machines, stepping will be still sligthly visible. And compared to Frosted, I don't see the difference.
