I've been using a 3/8" drive CDI Torque Wrench for several years now; a few complaints include the directional lever to change unintentionally while the torque wrench is being used and occasionally when torquing bolts / nuts down in tighter places, the torque value also unintentionally changes (1-2 ft lbs off) due to the placement of the torque adjuster mechanism. I usually don't mind using a vise grip to tighten the set torque value on the bottom of other torque wrenches; this CDI torque wrench has a mechanism in which you rotate the dial and once you hit your desired value it clicks back into place.
