TELESIN Smartphone Grip Magnetic Selfie Grip With Bluetooth Remote Control, Double-Sided Magnet Zoom Function, Front/Rear Lens Switching Two-Stage Shutter, Compatible with Smartphone Tripod/Monopod Includes Charging Cable and Strap Purchased new. Used twice, and I'm selling it because I don't use it much. Please see Amazon for detailed product information. I threw away the box. It attaches magnetically like MagSafe, so you can easily switch between portrait and landscape orientation. Being able to zoom and operate the shutter with one hand was particularly convenient. For iPhones, the zoom function is enabled by going to Settings -> Accessibility -> Zoom ON. The shutter part is detachable, and remote operation is easy. It can also be attached to a tripod.
