You REALLY shouldnt use a torque wrench to loosen ANY stuck bolts. The reverse feature is mostly so you have an idea on how much torque it requires to break it free.

When it comes to any wrench, I prefer only Mac or Matco. DEFINITELY worth the substantial price, especially as long as you dont lose it; lifetime replacement. Snap-On breaks too much and is too expensive for the same top tier quality as Mac/Matco
