Product Usage:
All AndyMark gearboxes require grease for proper operation and long life. We suggest using our red tacky grease, am-2768. We also encourage that the user powers the gearbox continuously for 30 minutes without grease to allow the gear teeth to wear in. While we do design with short run times in mind, this 'run in' period for smooth gearbox operation, is recommended. Once this is completed, thoroughly grease the gear teeth periodically to ensure smooth operation.

Toughbox Nano January 26, 2012
Reviewer: Anonymous Person from Dunlap, IL United States  
Large gears have a non-standard tooth profile where the first and last teeth cut overlap. Causes binding when backdriven - the jury is still out on the durability. Nice compact size and price.
