The hat recieved a lot if compliments. I have a larger head so the fit wasn't perfect, but it still fit comfortably. The battery doesn't last very long, about an hour or two before it started to dim until dead. It was mostly a gimmick type hat for my trip to Disney, but I thoroughly enjoyed it. If you wear a Medium sized hat, the fit should be perfect for you. I typically wear a large and the lines were more noticeable. Even still, it was worth the money.
