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.
