Review on WINSINN Aluminum Synchronous Timing Printer Power Transmission Products by Chris Parrott

Having assembled a number of 3D printers and now my CNC, I know what a good pulley is. It's not like this. It feels like cheap molded plastic painted silver to make it look like aluminum. It works. Its durability remains to be seen. Unfortunately this size is hard to find as they are not common. I'll have to look elsewhere for better ones and hope they last until then.
