Great price for 3 blades. The installation is quite easy. A problem. They are all "inside out" when shipped from the factory, so the teeth are pointing the wrong way when installed. They must point in the direction of the arrows on the drive wheels. I had to twist and turn each blade. This is easy, but wearing gloves is recommended. Not sure, but maybe some saws work in the opposite direction, or maybe whoever welded them just screwed up. I can still recommend her.
