## Customer Reviews

### ⭐⭐⭐⭐⭐ Awesome tool.
*by A***R on July 22, 2021*

So I was installing a tow hitch on my truck. The install manual said I needed to torque the nuts to 380 ft-lbs. My 1/2" torque wrench only goes up to 250 ft-lbs. I was unable to locate a suitable tool at a decent price to complete this task. After watching youtube videos, I was able to determine I could use a breaker bar on the nut, slip this "big bertha breacher" over the breaker bar, and then connect the torque wrench to the "big bertha breacher." There is a math calculation to determine what torque setting to set the torque wrench to but putting the tools in that order, I was able to get the 380 ft-lbs as accurately as possible. I was way happier using this method than all the other advice I received from RV mechanics (use an impact wrench) to coworkers(put a big breaker bar on it and tighten it as tight as you can...) I think this tool is an amazing product. I found other tools online for heavy machinery (tractors, earth movers, etc) for the same purpose I used it for, but they were much more expensive and difficult to obtain. This tool is amazing. I am always amazed by one-of-a-kind tools people can come up with. I am very glad to have this tool in my tool box.

### ⭐⭐⭐⭐⭐ Superb leverage device
*by B***M on August 9, 2020*

Being a small woman, I need leverage when applying muscle to stubborn bolts/nuts. This breached bar is easy to use, compact, versatile, heavy duty, and easy to store/pack. I have both breachers, and while love is not involved, respect has been gained. The 1" ID bar is hefty enough to break ties if dropped on them, so take care. .. Especially if under a car with this thing above you-- because a trip to the hospital could result of it hits you in the head!

### ⭐⭐⭐⭐ It works!
*by G***N on December 30, 2022*

Works pretty well in certain situations, but mine came with lots of surface rust, so I cleaned it up and oiled it.
