PASS: wood drill bits. Cheap and they do the job. They are single-use for any substantial steel, though.
PASS: 12-ton shop press. I've had mine for 4 years and done many big jobs with it. My dad has one that's over a decade old and gets weekly heavy-duty use at the marina he owns.
PASS: Piston ring pliars. A bit more flex than I'd like, but they did the job with minimal drama.
PASS: Piston ring clamp tool thing (used to put pistons back in the cylinders). Worked great.
PASS: rubber mallet with rubber and plastic cap pieces. I've abused it quite a bit. Still going strong.
PASS: zipties in the giant bags or plastic jars. I use them all the time. They work just as well as any other in my experience.
FAIL: HF version of brillo sponges. Grit is lacking, they don't do E36 M3.
PASS/FAIL: multi-pack of wire/brass/bristle detailing brushes. They pass because they're like $1 for a pack of three of them. They're good for one or two good scrubbings of gunky engine parts before they start to lose their bristles though. I just buy 5 packs at a time and am set.
PASS: deep impact sockets. I've used the metric set for 4-5 years of rallycross and autocross tire changes. My lugs wore faster than the sockets.
PASS: engine hoist. When I got it one of the holes for the bolts that hold it together was drilled a few inches from where it should have been. I drilled my own and have hoisted a dozen engines with it since with no issue.
PASS: engine leveler: Not the smoothest operation of the leveling crank, but it does the job with some elbow grease.
PASS: tripod engine stand. I've built two BMW M42s on it and it's fine. For a bigger engine I would go with a heavier-duty one though.
PASS: magnetic tool strip things. I have a few on my workbench that hold drill bits and stuff. They hold the stuff, so I guess they work :)
FAIL: grinder/cutting wheels. Single-use at best, even though they're cheap. I get name-brand ones at Home Depot now.
PASS: wire brush combo pack for drill. They're pretty stiff so I don't use them on softer materials. But they hold up to some heavy rust removal just fine.
PASS: 3/8 drive torque wrench. I use it for small things and my ghetto calibration calculations show it to be accurate. Wish the settings went lower for really small things like timing case M6 bolts though.
FAIL: orange ratcheting tie-downs. Had two of them pop open on the road, and almost lost my rally tires from my trailer
PASS: 10gal air compressor. Sat in the box in my uncle's farm field for 2 years before he gave it to me. Box practically fell apart. Compressor has worked great for the last year for small jobs, filling tanks, some air tools.
PASS: Pittsburgh brand tools (various): generally they've held up about as well as standard Craftsman stuff in my experience. A few other brands I've gotten at HF don't hold up as well, but I can't recall what they were called.
