When I wrote my comment I was thinking of the municipality workers with these gadgets in my area, sometimes using no ear protection! Hardly anyone at home, where there’s mostly just small gardens, uses these super noisy things.The city council probably thinks that they are saving a lot of money and time and giving their workers a much easier time. And like I wrote : I’ve read that devices running on electricity are quite silent. If there can be electricity poles for E.V. why not for this ?
