Is Harbor Freight torque wrenches good?

How do I know if my torque wrench is accurate? Hang the loop end of the rope on your torque wrench where you made your mark in step one (15 inches for us) so that the weight is now suspended. If your torque wrench clicked once, the weight was applied, then set it to 26 foot-pounds. If it did not click, then your torque wrench is accurate already.
