Even R1 Smart Ring vs Marine Band for Galaxy Watch Ultra and Galaxy Watch Ultra2 M/L: which is safer?

Where these two actually differ

• We flag Band material variability and Skin sensitization from sweat pooling on the Even Realities and not on the Samsung.
• We flag PFAS in fluoroelastomer formulation and Polymer degradation and particle release on the Samsung and not on the Even Realities.
• The Even Realities is titanium, stainless steel, sapphire crystal where the Samsung is Fluoroelastomer with stainless steel hardware, which is most of the difference in these two grades.
• The gap is 45 points, wide enough that this is not a close call, and the Even Realities is the one to buy.
• We are less certain about the Samsung grade, at 45% confidence against 72%, because it discloses less.
