Well designed, quite esthetic and ergonomic...but useless. Just after the warranty expired it sputtered gave up a a plume of white smoke and went into a deep coma.
The Canada wide chain store whence it came from referred my daughters to a repair shop with much expertise with these machines. After a few days, the shop called back, the machine was fixed and a clean bill($$$) of health was given.
Home they came, the grass they began to mow. After a few laps, a puff of white smoke (now we are not at the Vatican and no Pope was being elcted) came out and the machine went dead once more.
Now it lies amongst the ferns, a monument to poor workmanship and planned obsolescence, until some ecological way is found to get rid of it.
