quite pleased
I didn't buy this for the "protect" portion of the set, only the allergy testing solution. I haven't tried the protect solution. I've suffered from nickel allergies as long as I remember. Wearing anything with metal, from eyeglass frames to belt buckles, was always a gamble. I used this to test a buckle on a new pair of shoes before I wore them. I am happy to report that there was no nickel. I couldn't quite believe the results, so I started testing things that I know had nickel in it - like, a nickel. The q-tip turned bright pink, which is what it's supposed to do when nickel is present. The smell of the solution is horrible, and it started to set off my asthma, but I kept it well away from my face and everything seemed ok. Also, it did not ruin the metal on the shoe. I tested it in an inconspicuous spot because I wanted to return the shoes if they had nickel, but the solution didn't leave any marks.
