Mona W. Berlin: Unreliable car
I drive an "antique" VW Golf which had developed the habit of switching itself off. This happened, of course, mostly at traffic lights but also occasionally as I was driving along. Since I got my Harmony evolution, my Golf behaves again like a proper car.
Manuela F. Frankfurt: Electro smog
Due to electro smog my new computer would not work at all: The sensitive power distributor kept registering an overload and switching itself off. A Harmony evolution in the fuse box removed the electro smog from the entire flat and now everything works.
