### ⭐⭐⭐⭐⭐ Review
*by G***O on 9 October 2018*

Circuito elettronico semplice, ma ben funzionante e di facile regolazione (reperibili facilmente sul web le istruzioni). Vengono spediti 2 circuiti e due sonde ntc. Io ne ho usato uno per costruire un mini impianto di raffreddamento per un dvr (al fine di prolungarne la vita). Finora funziona perfettamente.Ottimo rapporto qualità-prezzo.
