Summary
4.6 stars across 2,400+ reviews. Professional mechanics and industrial users trust CDI (a Snap-on subsidiary). The wider 30-250 ft-lbs range covers lug nuts through axle nuts. Build quality is noticeably better than budget options. The price premium buys you tighter accuracy and a sturdier mechanism.
