Review: This unit is super solid and is a great price for what you get. Gearbox comes fully lubricated and is factory sealed. so don't expect to open it easily (not that you'd need to). It's full of oil and you'd need to remove the rubber gasket without damaging it somehow. The biggest issue I had was finding the appropriate hardware for driving the input side of the gearbox. The main input has an odd inner diameter of 11mm (7/16") with a 4mm wide key and I underestimated how hard it would be to find appropriate components to drive this with a larger shaft. With that said, the manufacturer included coupler that adapts this down to an 8mm d-shaft and that fits standard sized servos traditionally used for this.
Review: I have been using this worm gear with a stepper motor for a couple of years. It is well made and has been working flawlessly since I bought it. If you need a gear reduction for a stepper motor, I can highly recommend this one.
