Pros:
molto piacevole assemblare questo piccolo alimentatore regolabile. occorre pazienza per rimuovere le protezioni della plastica. i pezzi combaciano perfettamente. per montare i pulsanti ho dovuto montare al contrario cioè sotto sopra il circuito. alimentato a 12v arriva al massimo a 9v come alimentatore "didattico" è perfetto. rapporto qualità prezzo eccellente
Cons:
tensione in uscita massima più bassa dell'ingresso

Pros:
Works as expected. Easy to assemble. Good build quality. Useful to have both the voltage and the actual current in the display.
Cons:
Not really a con if you like to build, but the case have to be puzzled together by yourself. No user manual or building instructions in the package. (but its easy to build and the usage is mostly self explaining anyway). But some info could have been useful, like max input/output voltage and maximum load. Also some information about the battery ikon in the display.
