Review on Enhance Performance Tool W84006: Advanced Oxygen Sensor Thread Chaser for Optimal Efficiency by Matt Chirila

I have a 2001 Trooper with O2 issues. To say it fits snugly is an understatement. This tool makes life much easier. Really solid. Fits well on the small O2 head. I will say if you need a skinny socket this is not for you. It has a very good thick wall, I can't imagine that this tool can also be rounded with a wire hole. The curved shaft and reversible shaft make it very easy to find the right position and the long, straight end means you have room if you need to use a pry bar. I am a motorcyclist by trade and bought this for personal use but I can tell you it was made to a professional quality. Very satisfied.
