Helio Smart Ring Health Tracker, No Subscription, Monitors Sleep, Heart Rate & Stress, Titanium Alloy, Water-Res vs Helio Smart Ring Health Tracker: which is safer?

Where these two actually differ

• We flag Battery or internal component leakage and Dust and debris entrapment in band or seams on the Amazfit and not on the Amazfit.
• We flag Polymer band composition and residual monomers and Bacterial growth in sealed band-case junction on the Amazfit and not on the Amazfit.
• The Amazfit is Titanium alloy where the Amazfit is Titanium alloy case, polymer 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.
