This mount is for DJI's Mavic and Spark. Although the name says tablet mount, it can also be used comfortably with your smart phone. The arms on the Mavic and Spark controllers can stretch out far enough for any smart phone, but not every tablet. The base of the mount fits into the controller arms, taking the place of where your phone would normally sit. Attached is an expandable, rotating mount for your tablet or smart phone. This mount also brings your device closer to your face for better viewing.
