I'm just glad it was with a pretty cheap device and I have a bunch of replacements, I will probably open it up and have a look, may be something that can be fixed with a bit of jiggling.I suppose you're at risk of entering a sunken cost fallacy. Yeah, it's a tough one.

My main learning is not to use AliExpress for anything of any value, if I'd dropped 200 to 300 quid on a higher end device if be very annoyed, I kinda assumed it would be like Amazon, which is my mistake.
