Not specifically mine but definitely that of my wife: a company called Beurer in Germany makes this little tool with a small ceramic plate that you can heat. Press the hot thing against a mosquito bite and not only does the itch go away, the actual inflammation is diminished. For 20 euros one of the best impulse buys I ever did.

We’ve also put in an order for an electric bicycle which I think will lead to us leaving the car now often.
