Has to be 5 stars because the product did exactly what it was advertised to do!<br /><br />I was dealing with a rounded out sparkplug on a Durango V8 and really didn't want to break the ceramic top and try to use an easy out as I have seen in some videos of others in my predicament. I had looked at Grip-Tite first, but was concerned about the plastic bit breaking and noticed many ordered this product when the Gip-Tite had failed.<br /><br />I will say need to put plenty of downward pressure and ensure you are square on the nut. I had two attempts where I was not being careful enough to do this and it slipped. However, go slow, press firmly and it will bite. When it does it's game over for the nut, screw or sparkplug!
