I purchased this lighter because a full sized Zippo would not fit into my cigarette carrying case. It fits perfectly, and works just as well as the regular, full sized Zippo. Obviously, since it is smaller, it needs to be refilled more often, but not enough to be bothersome. I refill this slim Zippo approximately once every week or so, and my full sized Zippo can go about two weeks before needing a refill. Not a big deal to me. As a woman, this Zippo also fits better into my pants pockets when I am not carrying my cigarette case and is less noticeable, which I appreciate. Overall, a very good buy.
