Charge 5 Unicorn Beetle PRO Rugged Case and Band vs Classic Plus Stainless Steel Magnetic Closure WatchBand for Apple Watch: which is safer?

Where these two actually differ

• We flag Silicone and TPU degradation over time, Skin irritation from residual manufacturing contaminants and Bacterial growth in band crevices if unwashed 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 Silicone/TPU band, polycarbonate case 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 42% confidence against 82%, because it discloses less.
