generally a torque wrench is going to be hit or miss. either it is good or bad. i have purchased a few cheap torque wrenches which i had calibration checks done on them and they were fine. just remember a torque wrench is NOT a breaker bar, don't drop them (they can be knocked out of calibration), and release the tension on them during storage (set to lowest possible setting). if you follow these simple steps a torque wrench will last forever. FYI, i am a former aviation mechanic and used torque wrenches more than ratchet wrenches on most days wrenching on aircraft.
