These wheels are no round. That means they will introduce all sort of problems into you prints. Save your money.

If you need pulley wheels this is the product you need. Amazon is getting difficult because there are so many vendors out there selling terrible products. So when I get a product that is correct and does it’s job I am starting to make a point to leave a review to help others avoid getting the wrong product by buying the right one first.

Price is fair and they worked, seem to be correct size, no damage to plastic wheels.

I purchased these as replacements on a Ender 3 Pro and they fit and functioned as they should.
