The ZHIYUN SMOOTH 4 is a smartphone gimbal for image stabilization. I received it from someone, but I haven't been able to use it properly, so I'm selling it. It can be charged. I believe there are no problems, but I don't have the manual and I don't know how to use it, so please purchase it only if you understand that it is being sold as is. There are some minor scratches, but there are no noticeable stains or damage. Thank you for looking.
