My Microwave Oven was begged from the estate of an aunt and she had it for at least 10 years. So I reckon it is 1990 vintage. Small, cheapo and nothing to look at, but as an engineer the beauty I see is in its function.

The best of it is she was not a genetic aunt but an old, very good friend of mother's, who I visited weekly to check on her, and do little things around her house. So every morning as I do the porridge I am still in touch with her. How's that for beauty?

By Contrast I had a functionally perfect kettle that switched off when boiled till it didn't, fixed it till it wasn't, got another identical one that lasted less time, replaced with a dispensing kettle that because of the complex functionality & limescale and I get 1/2 a cup or two halves or 1.5 cups! All in a shorter 20 year timeframe.

The GF is on her third microwave and third kettle in less time!
And my next car won't have a keyless ignition - I spotted how the criminals could get round that one and guess what? Insurance claims up fivefold last year.
Advice - wrap "key" in aluminium foil when in a crowd of strangers.
