A software developer made a Chrome and Firefox extension called Knockoff that automatically hides, grays out, or filters products from sketchy brands on Amazon, which highlights just how many shady brands are on the platform and how commonly they show up on searches for basic items.

Unless you know what you look for, choosing the white label products from Amazon can be risky. For someone like me with extensove experience working with China I can usually tell what is crap and what is good enough, but the average person might take postings at face value or choose a category of product that is high risk of causing harm (e.g. I won't buy any no name plastic or rubber items that come in contact with food)

I can give another good anecdote for this.

Crank shaft holder for Toyota/Lexus. You attach it to a breaker bar, that you can let pin itself against the frame or ground, while reefing on a torque wrench to get the crank nut back on - something like 283 ft-lb for my truck iirc. Not a small amount of force if something breaks or slips and things go flying.

One of the good, brand name options is made by Oni. It's also over $60. You can get a knockoff for between $15 to $25. The bad knockoffs are just the ring portion shoddily welded to the "arm" (where you connect your breaker bar), and those two halves often come apart at the welds under use. The good knockoffs are obviously cast as one piece from a mold that was probably made from an Oni or similar. They get a questionable dull black coating, lacking the polish and clean finish of the name brand, but they're still a singular solid tool.

Not knowing which one will hold up and which one might give you summer teeth is a huge risk for any uninformed home gamer just trying to DIY some auto repairs on the cheap.
