His one is Wingsland k3 which looks very pricey quadcopter, for 1469$ you are getting these features: 4K Full HD camera with 24fps 360 degree 3 axis gimbal App for Smartphone to connect Point of interest Heading lock Follow me GPS & Glonass Ultra Sonic and Vision Positioning Sensor
By the way it's not look to be worth.Features they are giving doesn't made it to more than 1400$.But i think they will change the price later because Wingsland m5 offer same features like 4K fpv video,follow me and poi etc..and it is priced at 599$ but it does not have gimbal, they says that electronic image stabilization also it have a smartwatch by which you can fly m5.
