Harbor freight fuel pressure tester leaked fuel into the gauge on first use. Gordon flashlight to replace my maglight with a torn rubber boot on the on/off switch the lense went foggy and it lost contact internally you had to smack it on something every now and the to get it to come back on,my mag light still works years later.Flat bar and 36 inch prybar bent them both and the plastic handle on the prybar came off.12v test light the clear plastic was way to brittle and it broke in half .HF multi meter the ends pulled off the leads. I can keep going, These things were not put to anymore abuse than my other tools. I didn't think you could mess up a partner or a flashlight I thought I was pretty safe there.Everyone has their opinion but mine is the quality of their tools is pretty poor.FWIW I have 40 year old Bosch and Milwaukee stuff that the switches, chucks, things that hold the blades on etc.are still working great.and I use my tools.
All those things you listed, you can tell they may be garbage just by looking at them.
I have a set of deep well impact sockets that have held up wonderful for 15+ years. $20.
Air cutoff saw, works great after 15 years. $7.
6-piece plier set, still good after 15 years. $6.
Paint/primer guns, they work well. $10-$20.
Punch set, 10+ years. Forget the purchase price, but cheap.
Engine hoists. An old orange one and a newer gray one. Very nice and only $179.
Shop press. Very durable and still going strong after many years. Forget the price.
12" sliding compound miter saw. Only a year old but works like a higher end unit. Around $200 iirc.
6" bench grinder. 30-some bucks and many years later, still good.
Metal chop saw. Several years and LOTS of chops on it, still works great.
I could keep going. I've got more good stuff than bad stuff, by far. The stuff that failed, I expected it to fail but gambled anyway because of the price. Some things you can look at and know right off the bat that it's best not to waste your time.
