I hope someone can answer this question for me because I can't find a single picture anywhere of the BACK of the device, the part that goes against the skin.
Is it made of metal? I have a severe nickel allergy, so I don't want to invest in a Body Media armband if it's going to give me a rash.
My Polar Fit chest band does not have any exposed nickel, so it works well for tracking calories burned during exercise, but I can't see wearing it all day long.
Let alone sleeping in it!
Thank you to anyone who owns a Body Media armband who can give me the skinny on what it's made of.
