Per Eric Simdt, CEO of Harbor Freight, the Daytona jack is built at the same factory with the same features as the Snap-On. Snap-On buys their jack from a distributor that buys the jack from the factory.
You see an awful lot of shops with Daytona jacks... and not just one, but several of them.
It's a moot point for me. My Sears jack that I bought about 1975 is still going strong.
