uxcell DC 6V 35RPM 3mm Shaft Mini Metal Gearwheel Gear Motor GA12-N20

Excellent motor: Tiny, strong torque, quiet.At 5V, it goes 28rpm

Great little motor with a lot of power. Running a wooden gear system with it, off of a nine volt battery. Doesnt get warm. Works fantastic for my application.

Good little gearwheel motors; I used one to make a home made watch winder, and it's been working quite well. Soldering wires to the short terminals is a bit tricky.

Used this in a special designed filament purge system for my 3d printer with solid state reversing motor that has now operated 3823 cycles with no problem.I would have given this five stars if i could find a connector to fit this tried a number of them none worked. It would help if the vendor would suggest or provide crimp connectors to fit on these tabs. I destroyed my first motor trying to solder to the tab using a temp controlled soldering iron. If the data on what it would require or connectors were furnished I would have given this five stars. Note to the vendor if you added these I think the value would increase and be worth a very small price increase to compensate you for the cost of the connectors.

The motor is only rated for 6 volts, which means that it's not very powerful. It's also not very adjustable. The speed is always going to run at 35 RPM, which may not be fast enough for some applications.In addition, the motor can be noisy. It's not a loud motor, but it's definitely noticeable. And the motor can be difficult to solder. The solder pads are very small, and it's easy to overheat the motor.However, the motor is very affordable. It's only about $10, which is not a terrible price for a small motor. So, if you're looking for a small, affordable motor, then this is not a bad purchase.Pros:Small and lightweightAffordableDurableLong lifespanCons:Only rated for 6 voltsSpeed is not adjustableCan be noisyCan be difficult to solderOverall:The motor is small with some flaws. It's affordable and durable, but it's not powerful, adjustable, or quiet. However, at the right price, it's not a bad purchase.

I use these on my RC model boats to operate radars, winches and control crane arms. They work without fail every time and are quiet as well. They also use very little power so the batteries last a very long time.

Great little motor for various hobby projects. I made a ghostbusters ghost trap for my boys for Christmas using 3 of these to open the doors. I also used one of these to make a "useless machine" (a machine where you flip a switch and an arm comes over and turns itself off). It's really nice for teaching the kids about simple electronics.https://www.facebook.com/pennell63/videos/10208431821057921/?l=4613931150809770392

Love these tiny motors. Lots of torque, and quiet operation because of the metal gears.
