One thing Fluke are not good at is customer service, at least here in the UK.
So (assuming your experience isn't an outlier) Fluke isn't good in the UK, when dealing with individuals, and Keysight apparently won't even talk to you as an individual anymore.
That makes me wonder: is there
any top-tier T&M manufacturer that's any good with individuals in the UK? Because if not, then I'm convinced that the problem isn't with the companies, but rather with the UK itself, and it would lead me to believe that the UK has managed to regulate itself into irrelevance as regards individuals, and might well be going in the same direction for everyone else.
