Those can be fine, accuracy-wise. But of very limited use. After
all, it's not difficult to work out what most appliances cost to run.

When I get around to it, I'm going to put it on my fridge for a few
days. I want to see exactly how many kWh it draws over a week or so. You
can't do that with a clip-on, because refrigerators run intermittently.

That's true - but what action will you take? You can hardly switch it off
to save energy. Unlike heating and aircon. If it's old a new one will
almost certainly be more efficient. But may cost more than it saves.
