DJI Official Store via Newegg offers its refurbished DJI Phantom 4 Quadcopter Drone with 4K Camera for $729 with free shipping. That's $20 under our mention from three days ago and tied as the lowest price we've seen for this model, new or refurbished. (It's also $130 under the best deal we could find for a new one now.) It features a gimbal-stabilized 12-megapixel camera with 4K video recording at 30fps, slow-motion 1080p recording at 120fps, front-facing visual sensors, 44.7mph top speed (in sport mode), live HD video monitoring, GPS navigation, microSDXC card slot, and up to 28 minutes of flying time per charge.
