Here is one of the reviews from Amazon. I am just wondering if it is true or not because I have seen, in some cases, you have to recalculate the torque when using an extender.
I hit upon the idea of using this device as a means of connecting my torque wrench to an open ended wrench in order to apply the specified torque. As long as you position the torque wrench at right angles to the wrench you are using, you will not add additional spurious torque to the setting you want - the theory being that the lever arm of the torque wrench itself does not change. I verified this by sliding the torque wrench up and down the main wrench handle and achieved the same result everywhere - i.e. no additional torque on the sensor and the setting of the torque wrench remains accurate
