Where these two actually differ
- We flag Microplastics from case degradation on the Mophie and not on the Withings.
- We flag Nickel release from stainless steel case (contact dermatitis), Silicone strap degradation and microparticle shedding and Bacterial or fungal growth in strap-case junction on the Withings and not on the Mophie.
- The Mophie is Plastic housing where the Withings is Stainless steel case, sapphire crystal, silicone/rubber strap, 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.
