Review title: Work well, but beware if you're allergic to nickel
Product review: I bought these for my girlfriend and they work excellently. The only problem is that after using one for a couple months the gold wore down and she had a bad reaction. She's highly allergic to nickel. I'm not bashing the product, if nickel is not an issue then by all means buy it. Just wanted to give people a heads up since this is a pretty common allergy.
