A610 Universal Waterproof Float Case vs Ripcord USB to 12V DC Power Cable for Tech 21 Fly Rig 5 Multi-effects: which is safer?

Where these two actually differ

• We flag TPE material degradation, Microplastic shedding and PFAS in waterproofing coatings on the Spigen and not on the Tech21.
• We flag PVC insulation degradation over time, Phthalates in PVC insulation and Contact dermatitis from nickel in connectors on the Tech21 and not on the Spigen.
• The Spigen is TPE (thermoplastic elastomer) with waterproof sealing where the Tech21 is USB cable with standard copper conductors, PVC or polyethylene insulation, metal connectors, 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 Spigen grade, at 42% confidence against 72%, because it discloses less.
