Good
Good value and do the job required of them.

Great for LEDs
Really useful, not just for motors as I am using them to dim some LEDs, run fine with 3v in

As described
Works very well. Beware, the connection markings are underneath the board, so bear in mind when locating

Quality
Very good quality and a great price

Almost ideal...
Used to control d.c. motor speed for a telescope drive.Worked well but note the output voltage is +V supply on both leads at 0% duty cycle and is pulsed to ground to achieve PWM. Depending on your circuit this may be a limitation.

Great value
Easy to set up and works well

Works but only from about 8 to 12.4 Volts
Built quality is OK. Price is good. Not sure why they need to ship 2 as its a bit of a waste but I guess it means I've got a spare. FYI there is only one cable shared between the two units, not that it should matter... cut it etc... ;)But real issue is it only provided 7.9 (ish) to 12.4 Volts. So rather than "Duty cycle adjustable 0%-100%" I would say its "64%-100%" and so I'm giving it 64% out of 5 stars... I say "ish" because the DC voltage was rapidly fluctuating between 7.8 and 8 suggesting its not stable.However for my application which was to drive a silent fan in an extractor assembly it was adequate and the price is peanuts. But with hindsight I'd go for a more expensive one that's proven to do the 0-100% range.

Can use a 5v usb-A charger as a power supply for fans.
5V usb supply into this module then a 12v fan yields great results.Controller and knob moves smoothly and mounts easily with included nut.With this simple setup, the fan is able to operate through a full range of RPM'.LED power indicator built into the PCB is nice and bright. It is easily visible when I poked a pin hole next to it and works nicely with a blob of semi-transparent sealer / glue to act as a diffuser.Good value items for your home project.Have since acquired more.
