Befenybay 2pcs 2GT Open Timing Rubber Belt Length 1.2Meter Width 6mm with 8pcs Copper Buckle for Ender 3 3D Printer (Open Belt)

While $5.89 is not a big deal, and Ill find some use for it, the HiLetgo 2000W PWM AC Motor Speed Control Module Dimmer Speed Regulator 50-220V Adjustable Voltage Regulator should not have been bundled or been suggested as frequently bought together as it doesnt work (by design) with this motor or any of the others manufactured/distributed by this company.

Belt slips really easy. Used it to make a mini-winch for my sons powerwheels and the teeth started slipping when pulling anything 15lbs or more. Have it adjust to put at least 20lbs or more of tension on the belt and it still slips. Using both belts for a single axle on two ball bearings and its still slipping. Id say its rated for handling about 1-5lbs of twisting force per belt.
