Quality where it should be. Not too much worm gear/adjuster play; Better than most. Doesn't open during use which is what I'm looking for the most. Next is the jaw capacity. It only goes up to 5/8β. And maybe wider. I found a 4" paramount that can open 3/4". I was hoping this would be. If so I would give 5 stars and that would be perfect. I also found a prototype with a slightly larger head but still 4 inches long and opening to 11/16. I'm not sure about the quality of the metal on the prototype. The quality of the metal on this 4" klien appears to be better so far.
