Review on 🔋 OTUAYAUTO Battery Terminal and Wiper Arm Extraction Tool by John Ortiz

I got these to remove the very stubborn wiper arms on my 2008 BMW Z4. First I thoroughly soaked the slots with penetrating grease and then pulled these pullers. It was pretty obvious the levers were tight and well secured and the pullers would need help. So the trick was to tighten the pullers firmly and then push the levers DOWN about 6 inches from the attachment point. This side load was enough to loosen the wedges. (It's also a good idea to mark the position of the wipers on the windshield with painter's tape so you can get an accurate angle when changing.) Overall, I'm happy with the tool. I'm sure the Bavarian version of this tool will cost $178.90.
