Review on Keyfit Tools BREACHER Leverage Extension by Andrew Krishna

The Big Bertha Breaker is an inexpensive and effective wrench extender. It also allows you to connect a power bar (not included) for as much extra leverage as you want. Big Bertha was good enough for the job I bought her for, but she is so versatile that she will be a permanent addition to my toolbox. This particular set was even more spectacular because it includes two Big Berts of different sizes. An alternative key extension for my job would have worked but would have been significantly more expensive.
