They've refused to provide updates to backers at all. They go months between vague updates with 0 (zero) hard promises or details. It's been about a year since the projected ship date.
In addition, the team has been deleting comments[1] left by backers eagerly asking when their glasses will ship.
I've contacted the team directly multiple times via email, and have received nothing more than PR-speak responses worthy of the greatest nonanswers ever. As a counterexample, the KeySmart[2] Kickstarter campaign forgot to ship my reward and it was resolved in under an hour over email (I am not affiliated with them).
I'll continue assuming my $389 is as good as gone till the product arrives.
