Product excellent value for money. Craftsmanship, serious hardware in robust potentiometer. The modular power up to 50W allows use in all the needs of the "small electronics". My soldering iron 25w max did not allow me to replace a component in my old HiFi amplifier. The Welleman allowed me the desoldering and to reunite another in less time than it takes to write .. Comes with a fine tip down, it may be necessary to adapt to other faults as necessary. A set of dedicated outages can be purchased in addition to a low price. I recommend this unit "go anywhere" to all handymen who do not want to ruin a more professional unit.
