The statement above is not quite true. For example the U217 is a zero cross IC control which keep the iron tip temperature at +/-2C. http://pdf1.alldatasheet.com/datasheet-pdf/view/26117/TEMIC/U217.html Has no digital control, nor any any display measurement, but need an inexpensive temperature sensor like KTY84. Analog solutions are as good as digital sometimes... :) Vasile > Also the ceramic heater heats and cools fast, i can say. > > The stand and general material quality is also good. > > The kind of device for 99USD is the best you can get for that price if you > won't pay more hundreds and get a more professional and complicated hot air > SMD (de)soldering station.
