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

At first I thought this item was defective as the instructions supplied do not even cover this model of lighter and you need to follow specific steps to ensure it is refilled properly . If you just add butane you will build pressure inside the lighter and get a huge jet of flame, but only for a few seconds. Instead, you have to open the cap, which opens the gas valve, turn the lighter upside down and start refilling, and then close the cap during the fueling process. Several cycles of this will force the air out of the lighter and ensure it is properly filled. After that, it lights up normally and lasts for a while. Separately, the filling tube can be turned at the bottom with a screwdriver to adjust the flame, but on me it was necessary. Remember that every time you open the cap of this lighter you will lose gas and fully inflate the lighter. Open it and light it immediately, then close it when you're done. If these guidelines are followed, this is a functional lighter that will last a reasonable amount of time for its slim size.
