Good quality, fast delivery. It will take some time until I assemble this (soldering iron died) but overall I am very satisfied

no EU plug as described, description in Chinese only
I replaced the weak Miki-Maus transformer with a 40 watt transformer. I also removed the weak LM317 control and installed three DC-DC converters instead. One with a separate rectifier so as not to burden the four diodes too much. Now I have three outputs: a 5 volt, a 12 volt and an adjustable output from 2 to 14 volts with the LED display. So the power supply can really be used and it also looks pretty.
