Helio Smart Ring Health Tracker vs Original HONOR Insix Smart Health Ring X1A-08/10/12 Works with HONOR Magic V3: which is safer?

Where these two actually differ

• We flag Polymer band composition and residual monomers and Bacterial growth in sealed band-case junction on the Amazfit and not on the Honor.
• We flag Nickel release from titanium alloy and Skin contact irritants from coatings or surface treatments on the Honor and not on the Amazfit.
• The Amazfit is Titanium alloy case, polymer band where the Honor is Titanium alloy ring body, likely ceramic or sapphire sensor cover, 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 68%, because it discloses less.
