BRINGSMART 12V 5rpm DC Worm Gear Motor 35kg.cm Self-Locking Reversed Mini Turbine Geared Motor for DIY Robot Rotating Table Door Lock Curtain Machine (12V 5rpm)

Good product does the job

Smooth and strong motor. More torque than I need for steering a trolling motor, but just the right speed (44 rpm). I added a hall potentiometer, 3D printed gears, microcontroller, and H bridge driver making it the perfect steering servo for my boat.

Great mini motor has plenty of torque for what I needed it for and the self-locking in place works very well.

Very low torque, stripped the gears on the first use, extremely loud for the short time it worked. Junk.

First one I bought didn’t last a year so I ordered an another one just didn’t realize I order from the same vender. The second one has been on for a couple months and hasn’t started acting up, yet! I don’t have a lot of faith in these starters. But who knows maybe I just got a bad apple with the first one. I’ll hold off on writing the review on the second one to see how it works out. I give it three stars because customer service was great!
