Counter counter anecdote, I was just tidying up the yard with my 18V whipper snipper and contemplating the fact that I bought it in 2012 and it hasn’t skipped a beat.
It is in rough shape, but it still cuts grass perfectly fine.
I have a wippersnipper from before I was born which runs perfectly today. It was left out laying sideways in the rain for about a month. Quick clean and a new plug and it was going again.
I'm sure the electric devices can run a long time, but when they fail, they tend to be not repairable.
Serious question, as I understand the ex-Japanese market rights were sold to a Chinese corp over two decades ago, and the in-Japanese consumer device market rights went to a different Japanse company several years ago too.
Apparently they've gone back to focusing on their roots?
