They arrived in good shape and work for an Ender3 belted Z axis upgrade.

A well-made product. Timely delivery (overnight than the expected time). Packaged well. Will recommend.

Great price on pulleys that are useful in Middle and High School science projects. These can be used with string or twine instead of a toothed belt.

Upgraded my Ender 3 with these pulleys. The belt tensioners came with toothed pulleys which were a constant problem (layer shifts). The prints with these are absolutely smooth and works great. A highly recommended upgrade that's even cheap.

This is a good set of pulleys that is very useful for a quick gear change ratio. I use them for getting a bit more resolution on telescope focusers controlled via stepper motors. They are true to size and can be bored out a bit larger if necessary depending upon your shaft OD. The included belt is fiber-based and flexible, not the steel core type that is prone to failure.

Exactly the right size for the Y axis motor on my Ender 3 Pro as my replacement motor did not have a gear attached to it

A couple of the bearing are a bit notchy, but that's not going to cause a problem for this application
