I bought a usb-c dock. Unfortunately it did not work with my laptop so I returned it. Azerty did quite some tests with other laptops. Everything worked.
They sent me a new one (3-4 months after I bought the original dock (I was not able to contact them earlier). This one also did not work.
It turned out that this particular dock did not match with this particular laptop. I bought another dock and only had to pay the difference. Great service.
