So - my experience w/ harbor freight vs. other:
As far as I can tell, their battery tools (at least the drills) suck. I'm on my third 12v Chicago cordless and it is dead as a doornail in < 1 year.
Corded low torque drill is great - brag crush I've ever gotten on a barley crusher!
Plastic hand squeeze clamps - broke both of mine - got me through a keezer build but snapped after that. Solid for 1 time use but don't plan on them working when you need them.
Mechanics oil gloves (long sleeve) - lasted a few major knot weed sprays, then started to leak. They protected me from pesticides and digging up my sewer pipe so well worth it.
Backpack sprayer was way cheaper and would be going strong ... Except I pulled off the gaskets on the wand end not paying attention. Not sure if I need a whole new setup or can just get the parts. I did stay 12 gallons of glyphosate and eradicate 40x30 of knotweed, and the next decent model from Amazon was > 100, so I call this a big win.
Circ saw is going strong. I've been happy with all their corded tools, especially cause I beat the sh*t out of mine. I burnt out a dewalt doing 1/4" or 3/4" depth cuts during flooring demo. The HF version has held up and was way cheaper.
Drill bits (booting, standard, otherwise) make holes but are nowhere as clean as high end big box versions (HD, lowes, other). Then again they are nowhere near the price. If you need a bunch of clean holes of the same size go with quality bits. Otherwise these work.
Best tarp prices I've seen period. They're tarps- same everywhere.
Their heavy duty casters were great price too, but haven't used them
Have their framing nailer and nails - paused while I contemplate building my walk-in and hydroponic bed frames.
Their worm drive clamps suck ass (pull apart very easily) - bite the bullet and pay extra for good ones from a trusted hardware store.
Cheap wet tile bench saw paid for itself on doing my bathroom. Willing to sell if anyone needs it
.
Break bleeder did some solid degassing for me.
Infrared gun thermometer is fine - these aren't very accurate though (regardless of where they come from). Suck it up and get a good instaread waterproof thermometer.
