Not terrible, but not great either!

Decent product but pulley retaining screw is smaller than pulley hole. Eventually the bolt wears out and makes a chirping noise when printing. I ended up removing the pulley and bolt and reusing the pulley and bolt from the original tensioner assembly.

Pros
  • Quick Change
Cons
  • Almost never

Pros
  • understandable even for the old one
Cons
  • some little things
