Zippo Butane Single Flame Insert is an attempt to modernize the traditional Zippo lighter by using gas instead of gasoline, which aims to increase its functionality in everyday use. This gives us cleaner burning, no gasoline smell, better wind resistance, the ability to adjust the flame, and greater efficiency. Cons: the insert does not retain the characteristic atmosphere of the classic Zippo, is sensitive to the quality of gas used (cheap gas may cause clogging), and works less efficiently in severe frost. To sum up, it's a good alternative for urban use, especially if someone is bothered by the smell of gasoline. However, for lovers of the original Zippo, it may not capture its unique style.
