We have a pretty fair amount of HF stuff. For us, the $ value is very good.
As others have said, you get what you pay for, and for us, HF quality is often fine.
We have lots of hand tools (hate having rusty hunks of junk in the bottom of the wifes mowing truck box that say "craftsman" or "snap-on" on them.
At one point, I was buying the dang claw hammers in bulk I think and just leaving a couple in every room we worked in.
Big stuff, I have the 14" chainsaw type concrete saw, the concrete mixer, the vibe compactor etc. etc. We could not afford to have bought the "good" brands, and we can buy and have them around cheaper then rent.
I think most the folks that have problems, and get aggravated tend to think they will be as good as the name brand stuff. I expect the stuff too work (and they have been great at replacing or refunding with zero hassle when it did not) but I do not expect it to be as nice as a name brand tool.
