With its impressive maximum torque of 5.5Nm available in 12 settings and relatively quick charging time, you might wonder why this Black and Decker unit doesn’t score more than two stars. The answer is size, as it’s nearly as big as a small cordless drill. Even with a three-position hinge, there are plenty of places on a car where you’d struggle to use this. A high price and almost complete lack of bits also limit its appeal.
