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.
A alternative that works well for me for many things is buying from Lidl. They source from China, or wherever, but through European importers. They have a three year warranty, parts or replacement at least for that period, their branded products meet EU safety standards, and are good value. Not everything is perfect, but I’d say that about 80-90 % of what I buy meets or exceeds my expectations. Selection is orders of magnitude lower than Amazon, Aliexpress, etc, but their online catalog is growing fast.
Tools in particular are great value, they have a great battery ecosystem for their power tools, and even have a prosumer line (parkside performance, the black ones), that are impressively close to pro stuff from DeWalt, Makita, etc…)
