I personally pieced this set together from 4 different sets to make this a perfect set. Each one of these wrenches ratchets exactly as it should, and they all engage smoothly. The 120xp wrench line always has at least a 3rd of the wrenches that do not properly ratchet or skip teeth, but this set was pieced together from 4 different new sets to ensure each wrench ratchets smoothly and engages correctly.
