This is the TILTA Advanced Ring Grip for DJI Ronin. I purchased it used and have used it a few times. It's in good condition, without any major scratches. I have confirmed that it powers on and functions correctly. The accessories included are everything shown in the photos. - Quoting from the official website: "The Advanced Ring Grip for DJI RS2 / RS3 Pro / RS4 / RS4 PRO allows for more flexible power supply to the gimbal, accessory mounting, wireless follow focus motor control, and operation of the gimbal body." Please examine the photos carefully before purchasing. This is a used item, so please refrain from purchasing if you are sensitive to imperfections. No claims or returns accepted.
