I should chime in here as I was actually in Denver recently and
almost got to go visit the Asius labs and meet Dr. Ambrose. (Didn't work out because of tight scheduling on my part).
But, I made contact simply by using the contact form on their site:
https://asiustechnologies.com (then click Contact from the top menu).
Here's the hours/phone/fax/email info:
M-F 9AM-9PM MST
T: 720-204-2676
F: 866-840-3864

I wrote to them to express my interest but also my confusion, as their current Store still lists what appears to be the 1st-gen model, and there was a
big blog update from Dr. Ambrose himself in March about all the advancements they had made, and that shipping would commence in April... (Not sure if they actually did commence in April, but that's what he was anticipating in March).
Anyway, I think everyone would agree that they should have been better with communication and updates, but if you're still interested enough (and/or concerned/frustrated), I would encourage you to reach out to them directly. They actually invited me to go visit their labs and try out the tech for myself, and even though I wasn't able to make it that day, they were still very friendly and responsive and made attempts to address my questions and concerns. They even offered to set up a Skype session if I wanted a more personalized info session.
So... Do with that what you will. Here's hoping they can catch up with demand!
