Must admit I was impressed when I had 100m x 40m of grass,saplings and brambles to get through but the grass was twice as tall and neglected. It did it no problem. The wire cord is more durable than the 4mm square section industrial line I use on the Heavy duty petrol strimmer and it vibrates less. Granted the cutting width is 2" less but it did it with ease. Great price for the performance and a must buy if you have strimming that requires some actual power
