No bigger than a water bottle when folded, this “personal drone” is packed with features

DJI’s new “pro-sumer” drone, the Mavic Pro, crams lots of excitement into its compact size. Unlike other, more confusing foldable drones, it’s a snap to fold or unfold.  Yet, at $999, including a light yet rugged remote, it’s not just a toy.  The Mavic Pro can climb at 16.4 feet per second up to 1,640 feet, and can fly as far as eight miles away at speeds up to 40 mph, though you’ll start in newbie mode, at a top speed of 27 mph and max height of 400 feet.  Its camera features obstacle detection and gesture recognition, and shoots 4K video, stored or streamed.
