On paper, this is incredibly similar to our Best Buy. Jaw widths and opening are within a whisker of each other, and both worked smoothly and effectively. But while the Kennedy is a great piece of kit, it costs nearly twice as much as the Screwfix – and its only real advantage is a ball-joint that moves more freely.
