I am normally 100% Made in USA tool snob (I am guessing I am not alone here), but I bought the 20-piece set from Sears last summer, giving me one 10-piece set in metric and standard--one for the old BMW and one for the old Sunbeam to throw in the trunk.
Mine were Chinese made and seem okay for the price. Who knows how long the pawls and the ratchet teeth will last. Surely, in a pinch, on the road, they should be fine. But not as an everyday tool that gets used hard.
