Title: Bad wrench
Review: I like Irwin tools with the exception of this quick adjust pipe wrench. It just doesn't grip the pipe. Sure it's quick to adjust but it doesn't bite into a pipe unless you use two hands, one to squeeze the jaws shut and the other to pull. If you're using two wrenches to loosen tight fittings, then it's a complete failure.
