Review on 🔋 OTUAYAUTO Battery Terminal and Wiper Arm Extraction Tool by Duane Mann

This worked surprisingly well to loosen a stuck rusty wiper arm on my Audi S4. I sprayed it with lots of penetrating lube (good stuff. Kroil), let it soak for a day, went back and it came off right away with this tool. Is this tool for those incredibly stuck things you have? try again to free, no. Those who complain that it should have a hex head are beating the snot out of this tool, which it's not designed for. There are other tools on Revain that are not only far more powerful than this one, but also cost more than twice as much. Give this tool a try as it is well built, but understand, to loosen those really stuck wiper arms/battery posts, apply some penetrating lube first, hope this tool works for you.
