Review: This is definitely not a 12v motor. I bought the 3V version and a 12V version and they are the same. They have very low torque. Running these at 3V for some robot wheels may be fine, but if you actually need to move anything with a little bit of weight good luck. (Couldn't slowly spin a Raz Pi5 and a web cam even at the 16-30 RPM range).
Review: I submitted a question asking how I could mount this motor and gear box to a plate. After doing some research I found that if you do a search for "N20 motor mount" you will find motor mounts that are made specifically for all implementations that use this size (12mm) motor. Hope this helps everyone interested in items using N20 motors. Other than that, the motor and build quality appear very good. I did a test run and the motor and gear box were quieter than I expected.
