### ⭐⭐⭐⭐⭐ 







  
  
    As expected
  

*by J***B on Reviewed in the United States on August 14, 2020*

Quality seems on-par with the StepperOnline motors I've purchased. Lead screw is straight enough in both of the motors I got. I don't have an accurate way to measure it but I'd estimate maybe 0.25mm of runout at the tip of the screw.One thing to note is that the nuts are TAPPED for M3 screws, they're not M3 through-holes. This won't work with the majority of 3D printer designs if that's what your intending them for. The description doesn't specify this, but the photo does clearly show threads in those holes and apparently I was just too lazy to pay attention. Do yourself a favor a buy a set of Delrin nuts anyway, for this or any other lead screw stepper. They'll be quieter, never need lubricating, and the lead screw will never wear out.

    Easy Replacement for Makergear M2 Z-Axis, Big improvement
  

*by D***M on Reviewed in the United States on September 6, 2019*

Didn't want to pay retail for a Makergear replacement (original silver z-axis) so I started searching on Amazon. I got this one because of the advertised torque. So far its working excellent with the original M2 brass nut although I did have to increase current in Marlin firmware. The stock M2 wiring harness does not connect the same pins as the cable included with the motor. You can use the included cable but may need to modify your pre-existing wiring harness. Interestingly the Z-axis no longer drops when power is cut. It's quieter and stronger. Overall extremely satisfied.

### ⭐⭐⭐⭐⭐ 







  
  
    Good motor/screw
  

*by R***E on Reviewed in the United States on February 7, 2020*

Screw is strait and true, nut is well machined. Good product
