Greartisan DC 6V 100RPM N20 High Torque Speed Reduction Motor with Metal Gearbox Motor for DIY RC Toys

Nice tiny but powerful dc motor. Definitely does not run at the same speed with reversed polarity, but not a huge deal

Works good. I use it in my powder dispenser for reloading. Seems of good quality.

I used this to replace a failed motor on my FA Intellidropper. I'm not sure if the gearing is the same since I took off the old gear box and used this as a new motor. So far so good.

Overall, these are motors are pretty good. The only issue is the gears binding up and won't turn. My experience is 1 out of 5 will have this issue. I missed the window for returning one of the motors, but I'm returning at least one motor. They are good motors for the price but may not last long. I'll keep running the motors and update this review if any other issues come up.

I ordered this to replace a motor in an rc winch. It was the right size and the installation was easy. When I tested it, the winch had zero keep/brake. It would free spool. Update, the seller contacted me to troubleshoot and ultimately will replace. 2nd update, unable to send replacement. Refund provided. Great customer service!
