I have a pretty bad allergy to nickel and that is what most belt buckles are made out of.This belt solves that problem because the buckle is made out of some sort of hard plastic.It doesn't loosen and stays tight so I don't have to constantly tighten it like I did with my other belts.I've had the belt for around two and a half years and I've had no problems with it. does it's job just as it should.
