Bought as a gift for my son who is an engineering student. He loves to. Excellent control, fast temperature control. My only complaint is that the included solder wire itself doesn't have a so-called * in its core, which really is an absolute must for serious soldering. But he just throws away the included wire and buys a decent wire for a few bucks. Seems to be an obvious oversight that can be corrected quickly and cheaply in a quality set. this is the technical term for the rosin core. I am making this translation available for those of you who are not that tech savvy. :)
