Thank you for viewing. This is the Moment Mobile Filmmaker Cage for MagSafe. Its expandability and ease of setup with MagSafe are outstanding compared to other rig products, and it seems to be frequently used by professional photographers for iPhone shooting. Perhaps because of this, it's popular and rare, quickly selling out on the official website and becoming difficult to obtain. If you're interested, please consider purchasing it. ■ Usage Frequency I purchased it used in "like new" condition. Originally, the box has some tears and scratches from tape. The product itself has no noticeable scratches. ■ Reason for Listing I bought it intending to use it for filming, but it couldn't be mounted on a gimbal with the equipment setup I had planned. I haven't had a chance to use it independently, so I'm listing it for sale. ▼ Reference https://www.youtube.com/watch?v=YH32AH1Km1w
