StrapsCo Active Protective Case Strap for Fitbit Charge 5 vs Water Resistant Watch Model 8R500 - Men: which is safer?

Where these two actually differ

• We flag Bacterial or fungal growth (skin contact surface), Skin irritation or contact dermatitis and Material degradation and microplastic shedding on the Fitbit and not on the TomTom.
• We flag Polymer case and band degradation and Bacterial or mold growth in seals and band on the TomTom and not on the Fitbit.
• The Fitbit is silicone or elastomer strap, likely no intentional PFAS coating where the TomTom is On watch case and band, 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 TomTom grade, at 35% confidence against 72%, because it discloses less.
