Mr p body,, the tools are bought through companies that make a lot of tools you buy and pay more for,,
When Autozone first came out with the Duralast name branding,, those tools was made by Blue Point, the customer division of Snap On brand tools,
The same goes for Advance,
Granted almost all tools made now are made overseas, but the quality has risen a lot , can you get sub par tools From them ? Sure it is like any other item ,,, failures do happen.

I do not understand why some are taking issue over RENTAL/LOANER/PURCHASE of tools??
Best thing for those whom do not understand that concept need to go to the stores that do it, and ask,, look over some of the tools some are very very good quality, and the prices are very good whether you rent it ,, or keep it !
