Smart Silver Ring vs Even R1 Smart Ring: which is safer?

Where these two actually differ

• We flag Nickel leaching from unknown plating or finish, Coating degradation and unknown degradation byproducts, Heavy metal ions from base alloy or plating and Allergen contact (chromium, cobalt, or other alloy constituents) on the Livup and not on the Even Realities.
• We flag Band material variability and Skin sensitization from sweat pooling on the Even Realities and not on the Livup.
• The Livup is Stainless steel ring with unknown coatings or finishes where the Even Realities is titanium, stainless steel, sapphire crystal, 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 Livup grade, at 45% confidence against 72%, because it discloses less.
