I have been a NAASE and Chevrolet Certified Mechanic for many years and have had many ratchets, good and bad, from aftermarket discounts to tools for Mac and Snap-On. I have a 30 year old Snap-On 1/2 drive that still works fine, but this GearWrench ratchet is my new favorite. First of all, the number of teeth plays a major role. Less rotation is required to tighten bolts/nuts Secondly, unlike Snap-On, the gearing resistance is much less and works much better when the bolt/nut is free to rotateโฆ
