Helio Ring Size Smart Fitness vs Helio Smart Ring Health Tracker: which is safer?

Where these two actually differ

• We flag Polymer band degradation and volatile compound off-gassing, Contact dermatitis from band material or adhesives and Microplastics from band wear or degradation 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 ring body, polymer band 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.
• We are less certain about the Amazfit grade, at 35% confidence against 62%, because it discloses less.
