I have three of these I've collected over the last 3 years, and none of them work anymore.
Is this the new USB-C future we were promised? With a single-point of failure for everything as the number of ports on laptop decreases year-on-year?
I was gonna say, Dell makes a ton of crap but their dongles are solid. I've been using the DA310 "puck" for over half a decade and it still works like new. I think they're like 50 quid.
The other thing is to just avoid those no-name Amazon ones like the fucking plague. I've worked IT long enough to know that they pretty much all die within a year, that is if they function at all.
