Product review (5 stars): Better than original
In the first place as you probably already know the original rotor was a poor design because of the plastic teeth in the center. As much as a I think that it's ridiculous that I had to buy the entire rotor instead of the internal piece which has three screws on it and readily comes off, at least this one had a steel center piece in it. That is why I have to give it five stars. It was easy to install and is working like new. The old one was taken apart and is picking up screws and nails in my wood shop.
