Harbor Freight does sell many things that even a tool snob could use.
Their Pelican-style cases are pretty-nice, for one.
I rescued two kittens in the wall of my in-law's house using their fiber-optic color hand-held LED tv screen. I could hear the 'meow' & drilled a hole to find them in a void behind a faux fireplace. The LED tv showed a kitty staring back at me when I fed the fiber optic probe in. A sawzall hole through the kitchen closet wall allowed their removal.
They sell 'nite eiyz' products,
https://www.niteize.com/ which are varied and ingenious. I use their LED light w/a clip on it in flashing mode to keep track of the dog when I let him out at night to do his toilet business. Look at their SS carabiners and rope tighteners. I have multiples of each.
We were doing a whole-house remodel, the GC had $1800 budgeted for a crew to demo two baths to the CBS/stud walls & floor joists. I told him, "I'll do the job." I bought a HFT demo hammer/drill & SDS-Max bits, and saved $1600+. Since then it's fastened a 10' x 20' building to the new concrete slab for the build.
I have an orange small Chicago Electric side grinder that has lasted many years, and I do have multiple Milwaukee side grinders, that HFT has worked right alongside them w/no issues. Out of guilt, I checked the brushes the other day, they aren't even worn 1/2-way.
I have a set of forstner bit wood hole drills, they cut a precise hole, and are sized to my needs. I don't use them in a production role, but they have worked well for my home needs.
Every time I stop at one of the local HFT's, I always see multiple contractors' trucks in the parking lot, and employees w/named shirts inside, filling their carts w/supplies and tools.
But if you don't want to set-foot in there, that's more 'free, with purchase' stuff for the people who will visit, and will buy.
we were looking at the Harbor Freight ad today in a local paper while we were waiting for the rest of our party to arrive for lunch.
we saw those things - "free with any purchase" - but I couldn't think of anything I'd want to buy from Harbor Freight.
