The burnz-o-matic mini torch is a great little addition to anyones tool kit, It is shorter than an ordinary pencil, and no larger around than a bottle cap. It burns butane, and can be refilled through the valve on the bottom. It burns very hot, and one fill of butane lasts for about 20 minutes of burning time. Another great thing about this is you can buy a couple different attachments for it for different tasks, such as engraving, and soldering. It is simple to use except it doesn't come with it's own ignition system, which is the only bad point I can see. You turn the on/off dial until you hear the sound of gas coming out then light it with a sparker. It has a very simple design which makes maintaining it simple, and cleaning it is hardly needed, but it all comes apart for cleaning the jet and other parts which might get dirty if you need to. The additional parts range from 3-20 dollars, and in the package it comes with the torch attachment, and the torch. Butane must be purchased separately.
