The pickers fits, as expected, to my existing Gardena telescopic arm. He makes a solid impression and it works quite well. The built-in knife is indeed a good idea to work in practice, however, not optimal. But all in all I have a lot of apples, without a ladder, made entirely respectable heights (approx 3.5m - 4m) may present. An advantage of this system is that you do not have to re-make a complete switch in the shed, but that you may already complement existing equipment parts sinnvol.
