I tried them out at NAB. The quality is pretty nice in comparison to others I tried like Headplay, Eachine and Yuneec. The only disappointment is the lack of good diopler adjustment. You can use glasses OK, so I'm accepting the fact I'll have to find the right pair of reader glasses to fly with these goggles. What's very cool is the range they claim, saying they'll reach as far as the RC. We'll have to wait and see on that claim, but if it's really that good these goggles will be worth every dollar, given the resolution, 1080 for each eye, and the ergonomics. The flip up feature is great to look at the iPad quickly if needed. And connecting up to two goggles per Mavic, wireless, is very nice. I bought mine Monday morning, it said July 10th for shipment. We'll wait and see.
