IP68 Waterproof Phone Case, Underwater Snorkeling Case, Inflated Touchscreen for Diving vs A610 Universal Waterproof Float Case: which is safer?

Where these two actually differ

• We flag Elastomer membrane degradation and leaching under UV/heat, Microplastics from case wear or membrane fragmentation and Bacterial or mold growth inside sealed case on the Casebus and not on the Spigen.
• We flag TPE material degradation, Microplastic shedding and PFAS in waterproofing coatings on the Spigen and not on the Casebus.
• The Casebus is Plastic case with waterproof membrane where the Spigen is TPE (thermoplastic elastomer) with waterproof sealing, 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.
