It was purchased in April 2017 for a small flat garden of 150 square meters with grass.
Exactly three years later (May 2020), the motor burned out with smoke, after about 25-30 total mows,
mainly during the summer and with light use (low grass, no stones or wood, etc.)
In the end, it cost us about 4.5 euros per mow, about 40 euros per year.
I had bought it as a replacement for another electric one that burned out in a similar way, right after the warranty expired.
