It's buyer beware on Amazon. I only buy brand name products from them that I can't get at brick and mortar stores. The reviews are hit and miss, sometimes they complain that the product failed when they used it in a way that the product description said not to do, such as use on gas flame when the description said not to do.
My biggest complaint with them is the way they have jiggered Amazon Prime so that it's not worth the subscription price any longer. A lot of people are on automatic subscription from the days when it was worth it and haven't noticed the increased subscription price. Amazon is just another company out for a buck. Their changes in policies toward returning items is a new one. Recently, I ordered one thing and received a completely different item. Amazon referred me to the seller who told me to send it back to them at my cost. It took several rounds of dialogue before they gave me a refund. Like you, they didn't even want back the item they sent me.
A simple stratagem is to avoid “made in China” where possible.
If it’s not easy to determine country of origin, chances are it’s Chinese crap.
The one thing that takes a bit of homework is that many trusted G7 brand names slap their brand on contract-manufactured Chinese garbage. If they don’t make it obvious that (article) isn’t Made In USA/ Germany/etc., the usual reason is China.
Beware of “assembled in” products; they were manufactured in youdontwannaknow.
I think I’ll quit Prime. For me a draw was their streaming service, and it’s become almost entirely stuff I don’t wanna watch these days.
