Bought to replace my old portasol butane soldering iron which has served me well for several years. The only thing I didn't like about the previous model was that it was awkward to light as it had a flint igniter. I have used it exclusively on heat shrink tubing for my electronic projects. You had to either leave it on between heatshrink installations or turn it off and do the friction wheel procedure again. I have bought this newer model and a PPT-13 hot blow nozzle and every time it fires the first time with a click of the Piazo igniter. I leave the flame setting on the lowest setting as that's where it glows best. In addition, the setting is ideal for small shrink films. This model is perfect for almost anything, not too big to make it difficult to get to small places. I like it! And you can't name it by its quality and usefulness! Excellent purchase.
