From the moment you fill it, it holds very little in low intensity flame before it needs to be refilled. Its capacity is 5 gr and I found this out after weighing the gas bottle before and after filling the lighter. The metal body it has, which includes the ignition lever, means that after a short period of use, it starts to burn your hand. The flame intensity adjustment switch is located at the bottom and constantly comes off its position because it is poorly made. Overall, it is a cheaply made and completely unsuitable product for any serious use except occasional use with few requirements.
