Greartisan DC 12V 550RPM Gear Motor High Torque Electric Micro Speed Reduction Geared Motor Centric Output Shaft 37mm Diameter Gearbox

Works perfectly! Much more powerful than I expected.

This little guy is super tiny, yet an absolute BEAST. Manages to keep the 2.5 rpm (5rpm motor geared down to 2.5) while rotating the huge 26" diameter and over 30" long horn on my siren. 1/2 Scale ACA Hurricane MKII. $15 motor, comes to my door in like 2 days. Absolutely worth the money, great little motor. Uses M3 machine screws to mount it. With no load, it's pretty much silent. With a large load, it makes some noise but is still pretty quiet in general terms. When it's on the pole rotating the head, i can barely hear the motor at all. With the chopper running, it's literally impossible to hear this motor.

Well. So far. So good. I'm using this motor for a signaling Cannon I just finished putting together. It is raising and lowering the barrel. I wanted a motor with low RPM's and torque. This seems to be doing the job well at this point. If issues arise. I shall inform all who read.

Well Built Good Quality and Very Quiet. This is the motor I use for my spool rewinder. It has excellent torque. I don't need to say much just watch the video. I'll definitely be using this brand for other projects.

Very nice motor, plenty of torque. Size measurements provided on the Amazon web page were accurate.

works good

Very nice little power pack

I am using this for a Halloween prop where it hoists a spider (one of those 4 foot spiders you can buy at the Halloween stores) up to an overhanging branch on our front yard tree. The spider weighs about 13 oz and there is some friction in the system but the motor hoists the spider quite handily at about 0.5 m/s. It doesn't sound like it's struggling and stays cool. I'm controlling it through a Pololu motor driver and Arduino Nano and it seems to work fine with this setup. The motor makes a little noise but you can barely hear it out on the sidewalk. All in all very happy with this motor.

Perfetto per fare aprire e chiudere una porta da esterno con un telecomando e messo fine corsa in apertura e chiusura, lo consiglio vivamente .

The motor arrived quickly in good condition . It is very quite and works well . The only issue I had was I was not able to lower the speed with a motor speed controller. Over all it is worth the money

Bon moteur bonne finition fait pour des utilisations de comptage guidage. Je l'utilise en bobineuse pour micro et sa fonctionne très bien.

works as expected

This is being used to drive my Pastamatic (IYKYK) and is perfect. Paired up with a speed controller it runs smoothly and steadily from start to finish with no weird noises or smells. The 150rpm model runs the pasta at a slow but steady pace, if you are running the load on the spool to slow it down it will load up but not excessively. There is no prizes for speed, a faster one may be nicer but may lead to bad spool quality.
