I used it to install new switches on a keyboard. Purely amateur use and recent purchase, so I cannot comment on its durability over time. What I can say is that for soldering, i.e. melting the solder when placing the switch, it worked amazingly. It heats up quickly and melts the solder easily, both with the standard tip and with two aftermarket ones from Antex. For desoldering old switches that I tried, i.e. melting the existing solder, it is not powerful enough. But the tool is not responsible for this, I just needed something stronger. As I said, I cannot have an opinion on its build quality. However, when you hold it in your hands, it does not give the feeling of a cheap tool.
