Review on Gray Cigarette Shaped Butane Lighter with Gas Refill Function, Includes 3 Spare Flint Fire Starters - Ideal for Men and Women by Ann Champa

First it says it has battery life, it doesn't, although the battery life it says I assume is butane life. The question of how quickly butane runs out is easy to answer. It runs out pretty quickly, especially if you have a big flame, if you have a small flame the butane can last up to two days before needing topping up as I've found and this is with my brother who has it Used occasionally and repeatedly When smoking cigarettes it's a different matter when your flame goes out because the butane just before it goes out completely makes the flame massive, if you already have a pretty big flame that thing becomes a huge flame make as the foot is long, so be careful when using it, especially towards the end, apart from being easy to store, easy to fill and easy to use. It's small enough to fit in a cigarette box or cigarette case. Its flame is easy to adjust compared to other refillable lighters. I went and made sure I had butane for it by buying a few containers after finding out how quickly it runs out. The only other issue I had was that Flint's wheel is small, just like his Flint.
