Hi Guys,
I am looking for a cheaper alternative to those Reduction GearBoxes, since they are an important cost in the overall picture.
Anybody ordered one of those Gearboxes from AliExpress?

They have many Gearboxes like those. The more significant seems to be the max input RPM to be between 3000 - 12000 RPM’s.
For the price i believe this should be something worth trying.
