My cheap Irwin one is also a 2 jaw, but there is no comparison between the 2. everything is subpar on it. holding power is lacking, fitment is loose, the handle held in via ball detents is a good idea in theory, but I could see the stick slip of moving the handle with a small tap engaged, turning into a disaster. Handle is thin so it isn't comfortable to do several holes, back of the wrench is designed to take a socket of a square drive from a socket wrench, so no place for a tap follower, much cheaper chromed metal construction, etc.
