Review on 📷 Enhance Your Smartphone Photography with 20X Zoom Cell Phone Camera Lens and Monocular Telescope by Brad Schaefer

Very difficult to use as you have to remove the protective cover from the phone to ensure the correct fit of the lens. This can cause severe lens shaking. and it can only be used on old phones that only have a recessed rear camera, newer multi-lens cameras that are raised above the surface of the phone body will cause light to leak in around the base of the lens resulting in very poor image quality. Also note that the clip that attaches the lens to the phone can scratch the glass of the phone screen.
