This is a Smooth Q gimbal. I used it with an iPhone 12 Pro and iPhone 15 Pro Max, and it moves smoothly without being affected by the weight. I am selling it because I purchased a new gimbal. I mainly used it for my children's sports days and school performances, so the frequency of use was only a few times a year. The zipper pull on one side of the case is missing, but it can still be opened and closed. The case shows signs of use from being carried outdoors, and the main body doesn't show much wear, but some of the screw parts are silver. Please understand that this is a used item before purchasing. --- The following is quoted from Amazon ZHIYUN [Includes Japanese instruction manual, radio law certification, one-year warranty, and genuine product] Zhiyun Smooth Q 3-axis handheld gimbal stabilizer for smartphones, vertical and horizontal shooting, wireless control, supports phone sizes up to 6 inches, 8-hour runtime, buttons for photo/video/zoom (Black) Specifications Dimensions: 118 * 105 * 285mm Controllable Range: Pan: 360° Roll: ±30° Tilt: +185° -135° Runtime: 8-12 hours Operating Temperature: -10 to 45℃ Payload: 75g - 220g Net Weight: 450g (without battery & smartphone) Package Weight: 760g
