Product quite stunning: I bought it after much hesitation to mow approximately 500m2 of lawn, gentle slope, on a not very consistent over which pushes cow grass, clover, short, very far from a green Golf! Well, it's ultra-efficient: regular mowing, easy, you just push harder when it's very irregular or if the grass is really high. Frankly, I do not regret this purchase with virtually no maintenance compared to an electric heat or a fortiori. Very recommended!
