For being a very inexpensive machine, this little guy has definitely exceeded my expectations. I am very happy with this purchase. Do not use the solder wick that comes with it though ... it is complete garbage. Making my robots and circuits is SO much easier with this station. I have not used it a lot or for an extended period yet, but have used the rework segment for fitting heat-shrink, soldered with no issues at all (except the crappy wick they provide), and the power supply has been adequate for my needs (<10 V systems so far).
