My portable aircon unit thingy. Invaluable in Summer!
And my Remington hygienic trimmer .. it’s years old now but as you get older hairs start sprouting from random places!
My 14 year old car. Its old now but well paid off the initial layout (reasonable second hand for cash) years ago and so reliable. Every year she keeps running now feels like a free year. Long may she continue, I don't want another car.
