Works as advertised
Does what it's supposed to do; turns a cotton swab pink if the test object contains nickel. A bit expensive for what it is, but you only have to buy it once.<br /><br />The reaction is not instantaneous; you need to keep at it for a minute or so, and if the test object has only a small percentage of nickel the color may be pale and easy to miss.<br /><br />I found that an inexpensive watch that had given me a rash definitely had nickel.  The Nickel Guard seems to have fixed the problem.<br /><br />The &#34;Nickel Guard&#34; smells like nail polish, but I think it's a bit tougher and less brittle that nail polish.  Does what it's supposed to do.
