It would be helpful if the US labeled products as containing nickel the way they do int the UK. It's a nightmare allergy to have, further complicated by a lack of instructive labeling on food and other products. If we can do it for gluten and nut allergies we should be doing it for the  millions of nickel allergic folks out there. I don't know why more research is being conducted, as all of these  billions of laptops and cell phones are piling up in land fills and will be breaking down and eventually leeching into water systems. With Nickel allergies increasing yearly, that's a very scary future for us all.
