My Bottom Line on the value of Harbor Freight Tools:
Over the past 13 years, I have spent several $Ks on Harbor Freight tools. I have broken less than $100 worth of HF tools over this time. Since most of the HF tools cost less than 1/2 the cost of an equivalent name-brand tool, I am more than a few $Ks ahead.
There is a lifetime warranty on hand tools and a 30-90 day (or a year) on the other tools. I buy the non-lifetime warranty tools when I need them and I work them hard during the warranty period (in case they might break from being cheaply made). No problems.
