I've used it a few times and then put it away. I'm not using it anymore, so I'd like to pass it on to someone who needs it. The following is the product description from Amazon: This LUXSURE smartphone camera lens features a 2-in-1 design with a 0.6x wide-angle lens and a 15x macro lens. With MRC coating technology and a large-aperture lens, it enables high-quality photography without distortion or vignetting. It attaches easily with a clip and is compatible with almost all smartphones and tablets. The professional optical design allows for capturing clear, high-quality images. For wide-angle shots, you can get as close as 1-2cm from the subject to take even more beautiful photos. It has nano AR coating and also features manual focus. It's compact, measuring 3cm in diameter and 7cm in length, making it highly portable.
