Second one I have purchased. Good quality and work as expected.

Gearbox is fine, but the output shaft does not fit an extruder drive gear. I had to disassemble the gearbox and turn down the output shaft on a lathe in order to use it.

shipped fast, super quality, specifications shipped in package with it made it easy to put it online. Its past QA and has been on the equipment for three days with out missing a beat!
