Nickel Detection for Allergy Sufferers
Besides the horrendous smell of the product, it does the job.  Most importantly, it appears trustworthy.  It has detected nickel in items I was suspicious about and did not detect nickel in items I was concerned about.  Bought my daughter a watch and tested it before letting her wear it.  Product did not detect nickel and so far she's had no reaction.  Will be able to breath easier knowing I can prevent her from getting those horrible nickel reactions.
