Good product , come With a problem but only a one loose cable , not power on because this cable, fix open the item .
Basic rework station, with some caveats. The first is that at higher temperatures the metal tips will oxidize quite quickly getting dark and limiting heat transfer. The second is that the soldering iron tips are very light, and therefore have low thermal capacity. On one hand, that means quick temperature control but on the other means it is almost impossible to work with larger components, specially if high temperature solder is used, because it won't be able to warm everything enough quickly. The last one is that the hot air blower has some kind of sensor to detect if it is in use or resting but the provided stand not always work meaning that a few times it'll remain active if you do not place it very firmly in the stand. The temperature was measured with an external thermocouple and was found to be within +-5% of the temperature indicated in the display. In the end, a basic rework station, with good temperature control, perfectly usable and for an affordable price.
