Great reliable serious reliable seller !!!

chris bordeleau – 27 Jul 2016

this motor worked great... plenty of torque and average noise for these motors... I'd buy another if I needed one

Alex – 05 Dec 2015

Seems solid, disassembled to inspect, planet gears are nylon, I hope it lasts long.
As expected, stepper is gear drive.
Includes data sheet, VERY useful.
Works great though, real ratio is 26 103/121 : 1
Using for single Z lift on small 3d printer for super high precision.
