Had a very, VERY stubborn wiper arm stuck on and couldn't get any of my 2 or 3 arm pullers to get a good hold on it. WD-40 failed me, nothing worked. This puppy got a solid grab on it and while the arm still resisted it eventually popped off. My ONLY complained is that once it's tightened on and I'm starting to have to put serious force on it, that tiny little bar starts to hurt the hand and it's harder to get a solid grip on. I might have liked a 6-pt star-shaped knob, like... on a propane tank or such maybe. But still, it worked where nothing else did, so it gets a solid 4/5. I'd give it a 90/100 if the scale worked that way.
