Re: Site for sore eyes.
Amazon shouldn't be liable for every single product sold on the site, however their liability should kick in once somebody (and just one person) makes them aware that something is not legit.
For what it is worth: https://www.amazon.fr/gp/aw/d/B0196H3BSA/
It calls itself a JYE DSO138 oscilloscope kit. It's not great, being basically the ADC of an STM32 microcontroller, but for poking around video signals and low frequency stuff, it will suffice. Besides, I wanted to have fun putting it together. Notice all the JYE photos, the serial number, etc. Well what arrived was very obviously a fake. I contacted Amazon, "we take this seriously" and "we checked our stock" and so on. The usual bollocks. I was invited to return my kit and they would send me a proper one. I'll give them credit, they sent the replacement straight away so I could open up both and check that I had all the right components (the kits had incorrect values but of different things so between them I got all the right bits). Why bother? Well you've probably guessed that the replacement kit was equally fake. At this point I forwarded my emails to JYE and told them to add Amazon to the list of companies selling fakes, and then I gave up. I wanted to build the kit, not run around in Kafkaesque circles. As it happens it worked first time for me (perhaps having all the right bits helps? ;-) ) and is what I wanted. Maybe this coming winter I'll try the DSO Shell, now I know I can get an original from Banggood.
Notice that this fake kit is still being sold, and is still paying itself off as a proper JYE kit. Notice also that my review pointing out it's a fake isn't there. I'll need to write it again and this time take a screenshot.
tl;dr: There are fakes on Amazon and when it is brought to their attention, bugger all happens...
