I use a cheap (47 EUR ) 858D clone I bought in my my local electronics shop with no problems, so far. It's really a big ?helper enabling to avoid mess on your pcb when it comes to removing microchips, relays, USB connectors, etc. I have just replaced, easily, a micro USB socket on my wife's tablet computer and a fried ?microchip IC05 in my Hi-band QDX transceiver . It's especially useful for removing these components , for soldering in the replacement parts I like to use a conventional soldering iron. But the hot air station would work equally good for that too. Good luck! 73! Linas LY2H
