I really need just 2 pulleys to drive my encoder, but ordered this set hoping to get at least 2 good ones. O boy, I was right. Everything on these pulleys shows sloppy manufacturing and poor material handling. Two pulleys have several teeth damaged, enough to affect the belt operation. Something pressed on top of the teeth, changing their shape. One of these pulleys was dropped making a big mark on the rim. All of the 5 mm bores are oversized. My 5.030 mm test pin easily goes through all of them. Lucky me, I don't need 5 mm bores, I will open them to 7 or 8 mm with a proper fit to the shaft. I should be able to make 2 usable pulleys out of this set. Sorry, I cannot recommend it to anyone else.01-20-23 Update. Following my negative review the seller offered to replace the whole package. I have received it and there is no damages on these pulleys. It is possible that I received a few bad ones, but the rest of them are better. Because of that I am changing my rating to 3 stars.
