for the price they are good. Not as strong as the brand I first thought. But that makes her look good. I wonder if they will withstand a rock or a bend in a wing. When installing, you need to knock out the two screws that attach it to the machine. In terms of service, the seller was first class. I received the wrong order the first time. Okay, anyone can screw it up. They did well for me with a little note I wrote, I want to give them 5 stars for their service, the product just didn't deserve…
