Fre Case for iPhone 11 Pro vs EvoClear for Apple iPhone 17 Pro: which is safer?

Where these two actually differ

• We flag Polycarbonate degradation under UV and heat stress and Synthetic rubber gasket degradation or leaching on the LifeProof and not on the Tech21.
• We flag TPU degradation and microparticle shedding and Volatile organic compound (VOC) off-gassing on the Tech21 and not on the LifeProof.
• The LifeProof is Polycarbonate and synthetic rubber where the Tech21 is polycarbonate and thermoplastic polyurethane (TPU), 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 LifeProof grade, at 45% confidence against 72%, because it discloses less.
