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

The lens filter has a cap on each side, one is clear and one is blue. The instructions don't tell you which side to stick the camera lens on, so you have no idea which side is sticky. The blue foil does not show where the guide points for position determination are, as the ring around the camera lens is also black. Once you remove the film, you commit. The protrusions on the protective film are not long enough to be gently held on the lens without leaving fingerprints on it.
