Hey Duncan,
I’m not suprised! 
If you’ve ordered any parts from us please ask in the chat and though it may take a moment for us to find whether we’ve got any information on them, we should be able to pull any relevant information that we’ve got. I’m actually quite impressed by the error at <5% for no-name brand components.
Exactly! If it works, it works. All the best with your projects everyone!
