Easy to install took less than 10 minutes with watching Youtube. Fits perfectly but becareful because the wiper blade arm fits both ways. However as it fits both ways when you install it and place the main arm back down on the Highlander pull the replacement arm to check it doesn't come lose. If it is coming out and lose then switch the direction and install it again with the same directions and check it again. Now it should not slip out when you pull it. I had this issue when installing it but I quickly figured the issue out. After, I tested out cleaning the rear window and all was good.
