Updating my review - 5 stars -> 3 starsThe plastic encoder cap broke off my motor. That part is apparently very fragile as in don't touch it and it wont break. I didn't feel, or hear the cap break so I'm unsure of when or how it occurred, but I strive to not abuse parts, no point in buying something twice. It doesn't appear that the plastic cap was designed to have hardly any durability.******** End of 4/13/2020 update **********No complaints so far. My application is a hobby hot air gun coffee roaster for which this motor drives the stir paddles. It runs for 10-20 minutes approximately every 3-4 days.The speed looks correct at 25 RPM.The torque is good. I didn't measure the torque, but rather selected this part based on its rating, which I needed to be about twice my previous choice of motors. Its working in my application.Use-case for the encoder has not been urgent, and thus its untested at this point.I was concerned about the lack of ratings at the time of this purchase, but its worked out fine, and I'm so far very satisfied.
