"I use this tool for maintaining a dodge diesel and various Subarus. It is a great wrench and will last a lifetime in a home shop environment. I have had the wrench for several years now and it still sounds new and has maintained it's high torque. Read other reviews at Amazon and you will find many positive comments, then return here to make your purchase."


"Initial use has been quite good. For us the main interest will be how long this tool lasts."
