After comparing various other DJI supplier's I was convinced that going with US Drone was the right step. The price was one factor that was favorable of course. Shipping and customer service was excellent. Quick shipping was right on.
Everything was spot on in the case. Registration and getting it airborne was completed in one afternoon.
Everything performs flawlessly LOVE IT!
