Product Review

Compare the pictures, you will find the difference between Rovtop phone lens and cheap lens.
Terrible issue on cheap phone lens:
1. Cheap glasses - Terrible vignetting and distortion
2. Not a real wide lens - Actually a lens for capturing blurred fisheye picture.

But Premium Rovtop Phone Lens:
1. Wider - After thousands of optical corrections and testing by Japanese designers, we creat we create a extreme focal length phone wide lens - A 16mm wide phone lens which can catch 2.5x more picture.
2. Clearer, more durable, but less vignetting and distortion - Aircraft grade aluminum, premium Japan SLR camera Multi-layer coating aspherical glass for clear and extremely reducing vignetting, distortion
