Cool post. Thanks

I am on their list of beta testers. So far it's been crickets since early June.
I understand the challenges of small teams and hardware development, but updates would be nice.

Nice project. Efficiency is the way to go.

I'm also on the Beta test list and have heard nothing. Still its an exciting project if it really works. Wish them luck.
