Works well so far.

This bolted right up to my Ender 3 Prro. The plug is the same, and it matched the polarity that the stock stepper used. You may need to reverse the rotation in software, so heads up there. Otherwise, it's pulling filament from a curved Bowden tube that leads to the dryer box that I keep active filament in with no problem - torque is not an issue as I've used it. I believe it matches the stock stepper's step rate, as well. For eight bucks, I lightened up my print head plenty with no evident sacrifice. Cheap, perfect fit, plug and play, super easy install.

I was initially disappointed in these as well. I tested them out by hooking them up to an Arduino UNO and L293D driver. They are very underpowered with that driver. Speed was good but torque was ridiculously low.I switched over to a DRV8825 driver and that made all the difference. I tested at 9 and 12 volts and motor is functioning great with very strong torque now. Under 9 volts, torque gets very weak so recommend 12 volts.In case you are having the same issue and are unfamiliar with the driver:https://lastminuteengineers.com/drv8825-stepper-motor-driver-arduino-tutorial/https://www.makerguides.com/drv8825-stepper-motor-driver-arduino-tutorial/Driver:https://www.amazon.com/gp/product/B07XF2LYC8/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1Power supply:https://www.amazon.com/gp/product/B08KXWZ274/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

1.5 A is too much for most hobbyist projects, but that is no fault of the part. Once I had a driving circuit designed that could drive 1.5 A the motors worked great and were also very accurate. From a hobby standpoint you should look for a motor that requires less than 500 mA.

Great for general purpose applications. Worked right out of the box.

Used 2 of the 3 of these on my ERC Tim Sav Pin Cutter and it's been operating well without issue for over 6 months. The steppers seem to be very accurate and I'm pleased with the smoothness of operation and the noise level produced.

I was having trouble getting a replacement motor for the y axis on my Fox Alien laser engraver. Since they don't publish part numbers or motor data I had to go old school and found the info I needed and this motor was a perfect replacement. Only thing is you might have to reverse the motor leads depending on which side you use it on.I'm very pleased with my purchase.

Packaged well and delivered earlier than expected. Comes with connecting wires. A good product with great price I can find at the time of order. Will recommend and buy again from this seller.

Replaced my filament feed stepper on my Ender 3. was quite impressed with the weight difference and I think it's helped with the quality of my prints. 132.8g compared to the original 285.0g ... almost 1/3 pound difference on my direct drive conversion. Every bit helps.

Works with Artillery Genius - but you'll have to save the screws from the former unit so that the circuit board has anchor points.
