From the DJI YouTube Channel:
We give casual drone users the changes to fly using the DJI Goggles for the first time anywhere. Experience this incredible new way to fly along side them.
B&H has the DJI Goggles available for preorder.
Note: My understading of the current drone regulations would make use of this device outdoors by the drone operator illegal in the U.S. unless a) flying under the Part 107 rule (requiring a remote pilot certificate) and b) a waiver for first-person view goggles is obtained. [Sean]
