Galaxy Note 10 Series Waterproof Phone Case vs A610 Universal Waterproof Float Case: which is safer?

Where these two actually differ

• We flag Phthalate plasticizers in TPU or silicone (if formulation undisclosed), Volatile organic compound off-gassing during manufacturing or storage, Mold or bacterial growth in seals if not dried after water immersion and Softening or degradation of seals under sustained heat or UV on the Samsung and not on the Spigen.
• We flag TPE material degradation, Microplastic shedding and PFAS in waterproofing coatings on the Spigen and not on the Samsung.
• The Samsung is TPU or silicone elastomer 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.
