Review on 🔍 Enhance Clarity and Reduce Glare: Thinkware CPL Filter for All Thinkware Dash Cams by David Gonzalez

Haven't decided yet whether to keep this filter on my DVR or throw it away. I like the idea, but not so much the implementation. I have a ceramic tint on my windshield and this filter works the same as polarized sunglasses - it adequately reduces reflected glare but leaves noticeable phantom rainbows in the image. I thought I might have a little misalignment, but after double checking, the vertical alignment notch is aligned as advertised. I wouldn't buy it again if it wasn't for an untinted car.
