I'm another southpaw, Jon. I struggle with scissors and with trying to work out which way to try to turn a tight screw to undo it...

I stopped buying Napolina tomatoes a couple of years ago. I've found Waitrose Essential plum tomatoes to be far superior and consistently cheaper. They are far more saucy, less likely to possess bits of skin and they're easy enough to snip up in the can. I think they're better than Cirio too. A scant half-teaspoon of sugar per can of tomatoes works absolute wonders in any dish... I won't buy canned tomatoes that contain anything other than tomatoes. No herbs, garlic or salt for me.

The ring pulls on cans of Morrisons mackerel fillets in olive oil routinely break. Grr.
