Just don't buy off Amazon. I buy electrical goods from other retailers because Amazon provided products are pooled with 3rd party products in their warehouses - which means lots of counterfeit electricals even if you select something sold by amazon directly. Not worth the danger of a fire in your home buying a shitty knock off full price off amazon.
All the other shit you can literally buy on Ebay - they're the same sellers reselling the same chinese crap. The reviews are meaningless.
I've used https://reviewmeta.com and its browser extension to get a corrected stars count after it filters out fake reviews. I don't know how good it is still today but it's something.
