Have a long Gritter used until there broke a wheel and was no longer to fix. In addition, every now and then strips showed the grass, because a scatter opening clumped, or to and I was not noticing. The dosage was probably always rather too much. This part I consume less fertilizer. One can adjust super easy, the quantity, the scattering length. Making it suitable for small corners, as well as for large surfaces. Batteries last forever for the demand. Bin done much faster than in the past where I took the beautiful paths. Now I'm even in tracks on the lawn, but faster and a lot easier, more accurate. Can only be recommended.
