I've just purchased a vernier-caliper

On the packaging it says "Made in China. All figures are approximate"

It doesn't give much confidence that the 100mm to 150mm +/-0.03mm figure is
accurate!

Yesterday in Lidl, they had one of these -

On their reduced shelves at just £5.59 reduced from £7.99. Identical
item, just a different badged name. I already had one, but it would
have been rude not to get a spare at that price..
