Luxe Fitness Tracker vs Classic Plus Stainless Steel Magnetic Closure WatchBand for Apple Watch: which is safer?

Where these two actually differ

• We flag Elastomer band degradation and skin irritation, Bacterial or fungal growth under band and Waterproof seal failure and internal corrosion on the Fitbit and not on the X-Doria.
• We flag Nickel leaching from stainless steel on the X-Doria and not on the Fitbit.
• The Fitbit is Stainless steel case, elastomer band where the X-Doria is Stainless steel, magnetic closure, 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 Fitbit grade, at 45% confidence against 82%, because it discloses less.
