I was a bit concerned that the dual tip torch was impractical or difficult to use in hard to reach places, but it showed impeccable results on my first use when needed was Install a low level electric water heater under a shelf in a closet. The extra heat sped up the soldering of the 3/4" copper leads. The rotary knob is great for controlling the heat. At the same time I purchased a 309336 Universal Torch Extension Hose from Worthington Cylinders and it was well worth the investment too. , Allowed me to to place the flashlight head in very hard to reach places which would be extremely difficult if it connected directly to the gas tank of the map I am very satisfied with this flashlight, highly recommend.
