Didn't have an allergic reaction
I've had this curler for just over a year before it broke.  But during that time I didn't have an allergic reaction to it.  The shape isn't as good as my old Kevin Aucoin, but since that ended up causing a nickel reaction and this one didn't I'll take it.  Ordering a new one now.  But only because it's the only one I've found that is nickel-free (and can be purchased in the US).
