UV Haze 010 Filter vs K&F Concept Waterproof Case for GoPro Hero 13 Black: which is safer?

Where these two actually differ

• We flag Polymer degradation and leaching under heat stress, Seal and fastener corrosion or degradation and Off-gassing of volatile organic compounds (VOCs) on the GoPro and not on the B+W.
• The B+W is Optical glass lens with multi-coated optical surfaces where the GoPro is Hard-shell polymer case, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
• We are less certain about the GoPro grade, at 35% confidence against 82%, because it discloses less.
