Flip Filters FLIP12 DIVE & DEEP Filter Kit for GoPro HERO5/6/7/8/9/10/11/12 vs Think Tank Digital Holster 5 V3: which is safer?

Where these two actually differ

• We flag Wear debris or microplastics from threaded connections and Bacterial or fungal growth in sealed filter housing on the GoPro and not on the Think Tank Photo.
• We flag Undisclosed water-repellent coating chemistry and Coating degradation over time on the Think Tank Photo and not on the GoPro.
• The GoPro is optical glass and plastic filter elements where the Think Tank Photo is Ballistic nylon, weather-sealed fabric, metal hardware, 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 Think Tank Photo grade, at 45% confidence against 72%, because it discloses less.
