Can't fault the mower, if you set it up right it will work and continue to work well. I had to add about 17 meters of wire to the 150 meter supplied roll to cover my yard front and back, it still works perfectly so the 24 volt loop will cover quite some distance. Works well in the rain with the rain sensor turned off, but don't let it go in to any deep puddles. I have mine hooked up to a solar panel, battery and inverter so the sun makes the grass grow and the sun also cuts the lawn. All for free once set up. It's kind of turned the process into just weed spraying occasionally. Love it.
