The dovetail quick release plate mount designed for use with the Ronin-M plate is a huge time saver. If you need a way to swap your camera from the Ronin-M to a tripod you can leave the DJI plate on the camera. This plate will lock your camera down and keep it locked in place. Shoot from your tripod, than move right back to the Ronin-M without having to rebalance. The quick release plate monut has standard mounting holes so you can attach it to any video head. If you are shooting with one camera this can save you a lot of time. Here are some more images showing the other sides below.
