Works great to cool Raspberry Pi PiHole build.
Works great to cool Raspberry Pi PiHole build. Control range is accurate and I am able to control 2 fans per dial.

Works exactly as I wanted but untidy finish to product.
This is really good, most fans come with a speed set too high, for whatever reason manufacturers wont make slow spinning fans, it works as expected, attenuating the power of the fan, spins slower, less noise and dust. Fan speed is not linear with fan performance, as an example, half speed typically loses only about 5-10% performance. My only reason for not giving this 5 stars is that the PCB is exposed, a shell casing would have been nice.

Did exactly what I needed them to do
I used one of these to control the speed of a small extractor fan, which I use to allow me to keep my Xbox Series X inside a cabinet - the fan runs at very high speed; much more than needed, so I added one of these to allow me to lower the speed to a quieter level - worked perfectly, and if I need to (hot summer days for example), I can increase the speed of the fan easily. They're not glamorous, but they worked - no complaints.

Como digo en el titulo, es muy util y empiezo por lo que a mi,en mi opinion de usuario no experto en nada,merece este producto. Bueno++++ tiene aparte de las funciones que describe, tambien la funcion de interruptor on/off, no he leido en su dedcripcion esa funcion, y es muy util tambien. Negativo---- su conector usb macho tipo A, está anclado a la placa de una manera muy debil y pobre, yo lo solucioné con un trozo de tubo termoretractil, si no al ser tan endeble, al conectarlo, con la presion se dobla ,y eso no me sirve, como digo com tubo termoretractil solucionado.

Regolatori di velocità perfetti. Acquisto spesso prodotti della RUNCCI e non mi hanno mai deluso. Robusti e funzionali nonchè versatili. Io ad esempio lo utilizzo per alimentare e gestire la velocità del vibratore inserito nello schienale della sedia da gaming. Per il mio utilizzo resta attivo anche 8 ore di fila e ad oggi non ho avuto problemi di surriscaldamento ma ho fatto un box con pad dissipante. Consiglio comunque, per chi dovesse usarlo esternamente, di creare o acquistare un box così da non incorrere in eventuali problemi di corto circuito se tocca parti che conducono dato che il circuito è interamente a vista. Il potenziometro è decisamente preciso, ho effettuato un test con strumento di misurazione ed è perfetto, i valori sono esattamente quelli dichiarati in descrizione. Consigliato.

Der Regler funktioniert sehr gut und erfüllt seinen Zweck. Eine kleine Gehäuseabdeckung für die Elektronik wäre zwar wünschenswert, aber bei diesem Preis kann man nicht meckern. Sehr gutes Preis-Leistungs-Verhältnis!

Fonctionne parfaitement en revanche faites attention si vous le mettez à fond ça risque de griller certains circuits.
